Highlights of Solar and Geomagnetic Activity -26 October - 01 November 2026

Solar activity was at low levels with nine C-Class flares observed.

Region 4561 (S11, L=28, class/area=Dai/030 on 26 Oct) produced the

largest event of the period: a C2.8 flare at 26/1840 UTC, as well as

nearly all of the remaining C-class flares of the period. The only

exception was a C1.5 flare at 26/0134 UTC from Region 4560 (N13,

L=49, class/area=Fao/020 on 26 Oct). The only notable CME activity

was from a filament lift-off at approximately 26/2142 UTC from an

area near N30E75. Analysis indicated mostly a miss, though a

glancing blow was not ruled out of the question on 31 Oct. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at

high levels throughout the period, with the exception of 31 Oct when

values dropped to moderate levels. 

Geomagnetic field activity was at quiet levels 26-29 Oct, quiet to

active levels on 30 Oct, unsettled to G2 (Moderate) levels on 31

Oct, and quiet to G1 (Minor) levels on 01 Nov. Activity increased

the last two days as a result of the onset of a positive polarity CH

HSS combined with possible CME effects mixed in from the 26 Oct

filament eruption. 

Forecast of Solar and Geomagnetic Activity -02 November - 28 November 2026

Solar activity is expected to be predominantly at low levels, with a

slight chance of isolated M-class

(R1-R2/Minor-Moderate) radio blackouts) flare activity associated

with any developing spot groups during the period. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is

expected to be at moderate levels on 02 Nov and 06-18 Nov. Flux

levels are anticipated to reach high levels on 03-05 Nov and 19-28

Nov. 

Geomagnetic field activity is expected to be at mostly quiet levels

on 03-04 Nov, 08 Nov, 13-15 Nov, and 20-25 Nov. Unsettled to active

periods are anticipated on 02 Nov, 05-07 Nov, 09-12 Nov, and 26 Nov.

An increase to G1, possibly G2, geomagnetic storm levels is likely on

27-28 Nov. The increase in activity is associated with multiple

recurrent coronal holes.

Highlights of Solar and Geomagnetic Activity -19 - 25 October 2026

Solar activity reached moderate levels on 19 Oct when Region 4551

(S15, L=102, class/area=Eki/620 on 15 Oct) produced an M1.6/1n

(R1-Minor) flare at 19/0903 UTC; the largest flare of the week.

Solar activity was at low levels throughout the remainder of the

week. No Earth-directed CMEs were observed. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at

normal to moderate levels on 19-22 Oct, with high levels observed on

23-25 Oct. 

Geomagnetic field activity was quiet on 19 Oct through much of 20

Oct under background solar wind conditions. Unsettled levels were

observed late on 20 Oct following the initial onset of positive

polarity CH HSS influences. G1 (Minor) geomagnetic storming was

observed on 21 Oct, with active conditions observed on 22-23 Oct,

due to sustained positive polarity CH HSS influences. Quiet

conditions were observed on 24-25 Oct with the return of an ambient

solar wind environment.

Highlights of Solar and Geomagnetic Activity

05 - 11 October 2026

Solar activity was at very low to (R1-R2 - Minor-Moderate) levels

throughout the summary period. Region 4545 (N17, L=222, class/area

Dso/070 on 08 Oct) produced an impulsive M1.0 (R1 - Minor) flare at

05/1848 UTC. Region 4547 (N15, L=274, class/area Cri/030 on 06 Oct)

produced an M1.3 flare at 09/1409 UTC as the region exited the west

limb. The majority of the activity was observed from Region 4549

(N10, L=216, class/area Eki/260 on 09 Oct). During the period, the

region produced 39 C-class, 3 R1-Minor, and 2 R2-Moderate flares. It

produced an M6.7/2b flare at 08/1548 UTC with an associated Type II

Sweep with an estimated velocity of 4,125 km/s and a Type IV Sweep.

At 10/1510 UTC, this region produced an M6.4/1n flare with an

associated Type II Sweep with an estimated velocity of 929 km/s and

a 240 sfu Tenflare. The largest region on the disk, Region 4551

(S15, L=102, class/area Eko/400 on 11 Oct) produced 3 C-class

flares. In total, 50 C-class and 7 M-class events were observed. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached

high levels on 05-08 Oct and 10 Oct with a peak of 11,300 pfu

observed at 08/1250 UTC. Normal to moderate levels were observed on

09 and 11 Oct. 

Geomagnetic field activity ranged from quiet to G3-Strong levels

during the period. Quiet to G1-Minor levels were observed on 05 Oct

and quiet to unsettled levels were observed on 06 Oct, all due to

influences from a positive polarity CH HSS. Mostly quiet levels were

observed on 07-08 Oct. Activity increased on 09 Oct when unsettled

to active levels were observed due to weak influence from a 06 Oct

CME. Activity levels increased further on 10 Oct when unsettled to

G3-Strong levels were observed due to continued influence from CME

activity observed on 06 and 07 Oct. During this level of high

activity, total magnetic field strength increased to a peak of 45 nT

at about 10/1500 UTC and Bz observed some southward deflections to

30 nT at about 10/1630 UTC. Solar wind speeds rapidly increased from

about 380 km/s at 10/1500 UTC to a peak of about 890 km/s at 10/1755

UTC. Associated with this CME activity was some influence from a

negative polarity CH HSS. 

Forecast of Solar and Geomagnetic Activity

12 October - 07 November 2026

Solar activity is likely to continue at very low to low levels with

isolated R1-Minor levels possible throughout the period. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is

expected to be at high levels on 14-15 Oct, 23-28 Oct, and 01-04

Nov, all due to anticipated influence from multiple, recurrent CH

HSSs. 

Geomagnetic field activity is expected to be reach G1-Minor

geomagnetic storm levels on 13 and 31 Oct , and 01 Nov. Active

levels are likely on 12, 22, and 23 Oct. Unsettled levels are likely

on 14-15, 21, and 24 Oct and 02 and 06-07 Nov. All increases in

goemagnetic activity are associated with anticipated influence from

multiple, recurrent, coronal hole HSSs. The remainder of the outlook

period is likely to be at mostly quiet levels.

Highlights of Solar and Geomagnetic Activity 28 September - 04 October 2026

Solar activity was at very low to low levels throughout the summary

period. Region 4535 (N11, L=351, class/area Dao/060 on 30 Sep)

produced the strongest flare of the period; an impulsive C8.6/1f

event at 30/0246 UTC. This event also produced a 523 km/s Type II

and a Type IV Sweep. All other regions remained simple and absent of

any significant activity. No Earth-directed CMEs were observed in

available coronagraph imagery. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached

high levels on 28-30 Sep and 01 Oct with a peak of 5,620 pfu

observed at 29/1620 UTC. Moderate levels were observed on 02-04 Oct. 

Geomagnetic field activity was at quiet levels on 28-30 Sep and

01-03 Oct with some isolated unsettled periods observed early on 03

Oct. On 04 Oct, solar wind parameters became enhanced due to the

influence of a positive-polarity CH HSS. Total magnetic field

strength increased to a peak of 22 nT and Bz observed several

southward deflections, the maximum being -20 nT early on 04 Oct.

Solar wind speeds steadily increased from about 300 km/s to a peak

of 644 km/s later on 04 Oct. The phi angle was predominantly

positive. 

Forecast of Solar and Geomagnetic Activity 05 October - 31 October 2026

Solar activity is likely to continue at very low to low levels

throughout the outlook period. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is

expected to be at high levels on 06-11 Oct, 14-17 Oct, and 23-28 Oct

due to anticipated incluence from multiple, recurrent CH HSSs. 

Geomagnetic field activity is expected to reach G1 (Minor)

geomagnetic storm levels on 22 and 31 Oct. Active levels are likely

on 06, 21, and 23 Oct. Unsettled levels are likely on 07, 11-14, and

24 Oct. All increases in geomagnetic activity are associated with

anticipated influence from multiple, recurrent, coronal hole HSSs.

The remainder of the outlook period is likely to be at mostly quiet

levels.

Highlights of Solar and Geomagnetic Activity 03 - 09 August 2026

Solar activity was at very low to low levels throughout the period,

with no R1 (Minor) or greater events observed. Other activity three

CMEs associated with DSFs on 03 Aug, which arrived on 07 Aug, as

well as two CMEs without clear source locations on 04 Aug, which

arrived at Earth on 08 Aug. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at

normal to moderate levels throughout the period. 

Geomagnetic field activity reached G1-G2 (Minor-Moderate) storm

levels on 08 Aug following the arrival of CMEs that left the Sun on

04 Aug. Active conditions were observed on 03-04 Aug following the

arrival of a CME that left the Sun on 30 Jul. Quiet and quiet to

unsettled levels prevailed throughout the remainder of the period. 

Forecast of Solar and Geomagnetic Activity 10 August - 05 September 2026

Solar activity is expected to range from very low to low levels

throughout the outlook period. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is

expected to reach high levels on 12-16 and 22-23 Aug. Normal to

moderate levels are expected to prevail throughout the remainder of

the period. 

Geomagnetic field activity is likely to reach G1 (Minor) storm

levels on 11 Aug due to the anticipated arrival of a CME that left

the Sun on 08 Aug, and again on 19 Aug due to recurrent CH HSS

influences. Active conditions are likely on 10 and 17-18 Aug, while

quiet and quiet to unsettled conditions are likely to prevail

throughout the remainder of the outlook period.

Highlights of Solar and Geomagnetic Activity

20 - 26 July 2026

Solar activity was at low to R1 (Minor) levels this period. A total

of 54 C-class and 6 R1 (Minor) events were observed. The largest,

and most complex spot group, was Region 4493 (N06, L=158, class/area

Eki/440 on 23 Jul). This region produced a total of 42 C-class and 5

M-class events, the largest an M3.6 at 22/0635 UTC. A 200 sfu 10 cm

Burst was associated with this event. Region 4494 (S04, L=088,

class/area Dac/120 on 26 Jul) produced the other R1 (Minor) event,

an M3.2 at 26/1528 UTC. Associated with this event was a Type II

Sweep with an estimated shock velocity of 1,057 km/s. No other

significant activity was observed. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at

high levels on 20 and 26 Jul with the high value of 1,300 pfu

observed at 20/1645 UTC. 

Geomagnetic field activity was at quiet to G1 (Minor) levels. Quiet

levels were observed on 20 Jul. Levels increased to unsettled to

active on 21 Jul to early on 24 Jul, with isolated G1 (Minor) levels

observed late on 23 Jul. This activity was due to effects from a

negative polarity CH HSS. Quiet conditions were observed most of 24

Jul and 25-26 Jul. 

Forecast of Solar and Geomagnetic Activity

27 July - 22 August 2026

Solar activity is expected to be at mostly low levels with a chance

for moderate R1 (Minor) levels throughout the outlook period. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is

expected to reach high levels on 27 Jul, 02-03 Aug, 06-09 Aug, 12-16

Aug, and 22 Aug. The remainder of the outlook period is expected to

be at normal to moderate levels. 

Geomagnetic field activity is expected to be at unsettled to active

levels on 27-28 Jul due to potential weak CME effects. Unsettled to

active levels are expected on 29-31 Jul, 04-07 Aug, 11-12 Aug, and

17-20 Aug with isolated G1 (Minor) levels possible on 19 Aug. This

level of activity is due to recurrent CH HSS effects. Mostly quiet

levels are expected for the remainder of the outlook period.

Highlights of Solar and Geomagnetic Activity  04 - 10 May 2026

Solar activity reached high levels on 10 May due to an M5.7/2b flare (R2-Moderate) at 10/1339UTC from Region 4436 (N19, L=330, class/area=Dao/beta on 10 May), the strongest of the period.

Associated with the event was a Type II radio sweep (est. 650 km/s), Tenflare (550sfu), and a CME signature first observed in coronagraph imagery at 10/1348UTC towards the NE. Analysis and modeling of the event is ongoing at the time of this writing. 

Region 4424 (N17, L=192, class/area=Eai/160 on 30 Apr) also produced an M-class event with an M1.8 flare (R1-Minor) observed at 04/0133 UTC. The other 10 numbered active regions on this visible disk were either mostly quiet or only produced C-class activity during the past week 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels throughout the summary period. 

Geomagnetic field activity reached G2 (Moderate) geomagnetic storm levels on 04 May and G1 (Minor) levels on 05 May due to the influence of a passing CME. Total magnetic field strength only reached a peak of 11 nT during that time, but Bz rotated as far southward as -10 nT and was sustained southward from late on 04 May through midday on 05 May. Despite the influence of a positive polarity A coronal hole beginning late on 07 May, the mostly northward Bz component results in only quiet to unsettled conditions through the end of the reporting period. 

Forecast of Solar and Geomagnetic Activity 11 May - 06 June 2026

Solar activity is expected to be at low levels, with a chance for M-class activity (R1/R2-inor/Moderate), and a slight chance for X-class (R3-Strong), throughout the outlook period due to the flare potential of several active regions both currently on the visible disk and those expected to return from the Sun's  farside. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at high levels on 17-20 May due to the influence of a recurrent, negative polarity coronal hole. The remainder of the 

outlook period is likely to be at normal to moderate levels. 

Geomagnetic field activity is likely to reach G1 (Minor) geomagnetic storm levels over 15-17 May; active conditions are likely on 18 May, 23 May, 27 May, and 03 Jun; unsettled conditions are likely over 11 May, 13 May, 21-22 May, and 28 May - 31 May. All enhancements in geomagnetic activity are due to the anticipated influence of multiple, recurrent, coronal hole HSSs. The remainder of the outlook. The period is likely to be mostly quiet.

Highlights of Solar and Geomagnetic Activity 23 - 29 March 2026

Solar activity reached moderate levels on 26 and 28 Mar with low levels observed on 23-25, 27, and 29 Mar. 

Region 4405 (N26, L=178, class/area=Ehi/330 on 28 Mar) was the most active of the period, producing nine C-class flares and a long-duration M1.3 flare at 28/0416 UTC that was accompanied by a Type II radio sweep (estimated velocity 868 km/s) and a CME first seen in LASCO C2 imagery at 28/0336 UTC. Region 4403 (N16, L=206, class/area=Hsx/120 on 28 Mar) was responsible for the most powerful event of the period, an M3.9/1n flare at 26/0623 UTC, which was associated with a Type II radio sweep (estimated velocity 607 km/s), a 1,600 sfu radio burst at 245 MHz, and a CME first visible in LASCO C2 imagery at 26/0648 UTC. Neither CME was determined to have an Earth-directed component. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels throughout the period 23-29 Mar with peak of 12,800 pfu observed at 27/1515 UTC. 

Geomagnetic field activity ranged from quiet to G1 (Minor) storm levels. G1 storm conditions were observed 23 Mar due to the negative polarity coronal hole high-speed stream (-CH HSS) influences. Active levels were observed on 24 Mar under the continuing -CH HSS. On 25 Mar, G1 storming levels were reached again; while residual -CH HSS effects were present, the activity was primarily driven by the arrival of a CME likely associated with a filament eruption on 22 Mar. Conditions waned to unsettled levels on 26 Mar and quiet levels on 27 Mar as HSS influences subsided. Activity remained quiet to unsettled on 28 Mar. On 29 Mar, the field returned to active levels preceding a solar sector boundary crossing (SSBC) and the onset of a positive polarity CH HSS (+CH HSS). 

Forecast of Solar and Geomagnetic Activity 30 March - 25 April 2026

Solar activity is expected to be is expected to be at low levels, with a varying chance for M-class (R1-R2/Minor-Moderate) flares through 25 Apr. 

No proton events are expected at geosynchronous orbit, barring any significant, non-recurrent solar activity. 

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 30-31 Mar, 04-09 Apr, 11-16 Apr, and 18-25 Apr. Normal to moderate flux levels are expected to prevail throughout the remainder of the period. 

Geomagnetic field activity is expected to reach G1 (Minor) geomagnetic storm levels on 30 March due to the influence of a positive polarity CH HSS (+CH HSS). Periods of G1 storming are likely on 04 April in response to a negative polarity CH HSS (-CH HSS). Further G1 storm periods are anticipated on 09 and 11 Apr,

with likely G2 (Moderate) storm levels on 10 April, due to + CH HSS influences. The field is expected to reach G2 storm levels again on 18 Apr, followed by G1 storm periods on 19 Apr, due to -CH HSS influences. Unsettled to active conditions are likely during the onset and waning phases of these streams.

Highlights of Solar and Geomagnetic Activity 09 - 15 March 2026

Solar activity was at low to moderate levels with a total of 37 C-class flares and 2 M-class flares observed. The largest flares of the period were an M1.2 flare on 13/0955 UTC from Region 4384 (N10, L=150, class/area Eho/300 on 03 Mar), a C8.9/1n flare on 13/2023  from Region 4392 (S15, L=017, class/area Cso/170 on 15 Mar), and an M1.0/Sf flare on 15/0939 UTC from Region 4392. The most active region of the period was Region 4381 (N08, L=173, class/area Eao/220 on 03 Mar), which produced a long-duration C8.0 flare on 13/1518 UTC in addition to 11 other weak C-class events. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 09 - 13 Mar and 15 Mar with a peak flux of 2,940 pfu observed at 12/1545 UTC. Normal to moderate levels were observed on 14 Mar. 

Geomagnetic field activity ranged from quiet to G2 (Moderate) storm levels throughout the 09-15 Mar period. The week began at quiet to unsettled levels on 09 Mar, with active conditions observed on 10-11 Mar due to the influence of a negative polarity coronal hole high speed stream (CH HSS). Conditions returned to mostly quiet to unsettled levels by 12 Mar. Activity intensified midday on 13 Mar, reaching G1 (Minor) to G2 (Moderate) storm levels following the onset of a positive polarity CH HSS. These storming levels continued through the first half of 14 Mar before waning to unsettled and active levels later in the day. On 15 Mar, the field reached active levels early in the period, followed by a return to quiet and unsettled conditions as positive polarity CH HSS effects gradually diminished. 

Solar wind parameters reflected the influence of two distinct CH HSS regimes during the period. The week began under the influence of a negative polarity CH HSS, with solar wind speeds initially ranging between 450-500 km/s before gradually declining to ambient levels near 400 km/s by 12 Mar. Total magnetic field (Bt) remained mostly around 6 nT during this interval, while the North-South (Bz) component saw periodic southward deflections to -7 nT. A solar sector boundary crossing (SSBC) occurred early on 13 Mar, indicated by a shift in the phi angle from the towards to away sector. This was immediately followed by the onset of a more powerful positive polarity CH HSS. Solar wind speeds rose sharply from 400 km/s to a peak of 725 km/s on 14 Mar. During this period, Bt reached 13 nT and the Bz component reached a maximum southward deflection of -10 nT.

By 15 Mar, solar wind speeds began a slow decline but remained elevated near 600 km/s through the end of the period. 

Forecast of Solar and Geomagnetic Activity 16 March - 11 April 2026

Solar activity is expected to be at low levels, with a slight chance for M-class (R1-R2/Minor-Moderate) flares throughout the outlook period. Elevated probabilities are related to the flare potential of both currently observed spot groups as well as the potential from returning regions. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at high levels on 16-20, 22-30 Mar, 04-09, and 11 Apr due to the influence of multiple, recurrent, CH HSSs. The remainder of the outlook period is likely to be at normal to moderate levels. 

Geomagnetic field activity levels are likely to reach G1 (Minor) geomagnetic storm levels on 22 Mar, 04 Apr, 09 Apr, and 11 Apr due to CH HSS influences. G2 (Moderate) geomagnetic storm levels are likely on 11 Mar and 10 Apr due to CH HSS influences. Unsettled to active levels are likely on 16-18, 20, 23-27, 30-31 Mar, and 03 and 05-07 Apr. All elevated levels of geomagnetic activity are associated with the anticipated influence of multiple, recurrent, CH HSSs. The remainder of the outlook period is likely to be at mostly quiet levels.

Highlights of Solar and Geomagnetic Activity 26 January - 01 February 2026

Solar activity ranged from low levels to very high levels. On 26-30 Jan, mostly low level C-class flaring was observed with the majority of the flares occurring from Regions 4351 (S04, L=004, class/area

Dai/080 on 24 Jan), 4353 (N18, L=359, class/area Dai/110 on 25 Jan). The largest flare during this timeframe was a C8.8 at 26/1339 UTC from Region 4355 (S12, L=299, class/area Cao/020 on 25 Jan). On 30 Jan, a new region emerged in the NE quadrant and was numbered 4366 (N14, L=202, class/area Ekc/550 on 01 Feb). This region quickly grew into a large, compact, and magnetically complex region over 31 Jan-01 Feb. Multiple delta magnetic configurations evolved as the region grew. Consequently, there were 17 M-class flares and 2 X-class flares observed on 01 Feb. The largest was an X8.1 flare at 01/2357 UTC. Associated with X8.1 flare was observed three CMEs that appeared in SOHO LASCO C2 imagery beginning at 02/0048-0300 UTC which was also evident in GOES/SUVI 304 imagery. Modelling was currently underway at the timing of this report. 

A greater than 10 MeV proton enhancement near 1 pfu (below S1-Minor) was still in progress from the event that began on 18 Jan, but declined to near background levels by 28 Jan. 

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 26 Jan-01 Feb with a peak flux of 13,200 pfu observed at 27/1650 UTC. 

Geomagnetic field activity ranged from quiet to G1 (Minor) levels over the period. The period began under positive polarity CH HSS conditions with solar wind speed averaging around 500 km/s with total field around 5-8 nT. Solar wind conditions returned to nominal levels by early on 27 Jan. A solar sector boundary crossing from positive to negative occurred around 27/1500 UTC followed by an increase in total field to 13 nT and solar wind speed increase to around 670 km/s on 28-29 Jan as a negative polarity CH HSS became geoeffective. Solar wind speeds gradually subsided to nominal levels by 01 Feb. The geomagnetic field responded with quiet to unsettled

levels on 26-27 Jan, unsettled to G1 (Minor) storming on 28 Jan, quiet to active levels on 29-30 Jan, and quiet conditions on 31 Jan - 01 Feb. 

Forecast of Solar and Geomagnetic Activity 02 February - 28 February 2026

Solar activity is expected to continue at moderate to high levels with further M-class (R1-R2, Minor-Moderate) flares expected and a high chance for X-class (R3-Strong or greater) on 02-10 Feb as Region 4366 transits across the visible disk. Low levels with a chance for M-class flares are expected on 11-22 Feb. An increase to moderate to high levels is once again likely on 23-28 Feb as Region 4366 returns to the visible disk. 

The greater than 10 MeV proton flux is likely to reach S1-S2 (Minor-Moderate) storm levels on 02-04 Feb due to proton prediction model guidance from the recent X8.1 flare. A chance for further proton enhancements exist through 12 Feb as Region 4366 transits the visible disk and beyond. 

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 02-03 Feb, 06-12 Feb, and 15-28 Feb due to recurrent CH HSS influence. 

Geomagnetic field activity is expected to be at mostly quiet levels on 02-05 Feb barring the potential for CME activity related to the X8.1 flare. Quiet to unsettled levels are expected from 05-11 Feb, 22-23 Feb, and 26 Feb. Unsettled to active levels are expected on 13-21 Feb, and 24-25 Feb, with G1 (Minor) levels likely on 13 Feb due to recurrent CH HSS effects.
