Highlights of Solar and Geomagnetic Activity

31 August - 06 September 2026

Solar activity was at moderate levels on 02 Sep and 04-05 Sep due to

three R1 (Minor) M-class flares, and low levels on the remaining

days. The largest flare of the period was an M3.0 at 02/1920 UTC

from Region 4524 (N12, L=224, class/area Cso/100 on 05 Sep), which

was also responsible for another M1.2/1n at 04/0753 UTC and 11

C-class flares throughout the period. The M3.0 was accompanied by

Type II (estimated velocity 1181 km/s) and IV radio sweeps and a CME

first observed in LASCO C2 at ~02/1936 UTC, which modeling indicated

would pass behind Earth orbit. 

The last R1 was an M1.0/1f at 05/1518 UTC from Plage Region 4520

(S12, L=337, class/area Dai/40 on 01 Sep); this region had fully

decayed to plage on 03 Sep. An associated CME first became visible

in LASCO C2 at ~ 05/1800 and in STEREO coronagraph imagery at

~05/1608 UTC as a halo. Modeling indicated this eruption would pass

ahead of Earth orbit. 

Notably, Plage Region 4518 (N07, L=354, class/area Cri/30 on 26

Aug), which had fully decayed to plage on 03 Sep as well, also

produced a C1.3 at 04/1527 UTC. 

7 additional CMEs were observed this reporting period. Coronal

dimming seen in GOES/SUVI 195 starting ~02/0910 UTC was associated

with a CME first seen in STEREO coronagraph imagery at ~02/1108 UTC;

modeling indicated that the bulk of the material is likely to pass

ahead of Earth orbit but a glancing blow on 07 Sep was possible. A

C7.9/Sn at 03/1630 UTC from Region 4524 was accompanied by a Type II

radio sweep (estimated velocity 1359 km/s) and a CME first observed

in LASCO C2 at ~03/1636 UTC, which modeling indicated would not hit

Earth. A C6.7/Sf at 04/1930 UTC from Region 4524 was accompanied by

Type II (estimated velocity 698 km/s) and IV radio sweeps and a CME

first visible in LASCO C2 at ~04/1924 UTC and STEREO at ~ 04/2030

UTC; modeling indicates this eruption may swallow the 02 Sep

eruption and produce a glancing blow at Earth either late 07 Sep or

early 08 Sep. A north-south filament just SE of disk-center began

erupting at ~05/0530 UTC, and an associated CME was first observed

in STEREO coronagraph imagery at ~05/0638 UTC. A C6.4/1n at 05/1045

UTC from Region 4524 was associated with a CME first observed in

LASCO C2 at ~ 05/1112 UTC. A C8.5/2n at 05/1746 UTC from Region 4524

was associated with a CME first observed in LASCO C2 at ~05/1800.

Modeling indicates that these three CMEs may have a merged arrival

at Earth on 08 Sep. Finally, a C5.0/1n at 06/1042 UTC from Region

4524 was associated with a CME first observed in STEREO coronagraph

imagery at ~06/1053 UTC, which modeling indicates may produce an

arrival at Earth late 08 Sep or early 09 Sep. 

Proton levels at geosynchronous orbit rapidly enhanced on 05 Sep in

response to the M1.0 from Plage Region 4520. The greater than 100

MeV proton flux crossed the 1 pfu threshold at 05/1545 UTC, peaked

at 05/1550 UTC at 1.16 pfu, and crossed back below the threshold at

05/1615 UTC. The greater than 10 MeV proton flux crossed the 10 pfu

threshold at 05/1615 UTC, peaked at 05/1645 UTC at 18 pfu, and

crossed back below the threshold at 05/2135 UTC. 

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

high levels from 31Aug - 04 Sep and on 06 Sep, returning to normal

to moderate levels on 05 Sep. 

Geomagnetic field activity was at unsettled levels 31 Aug-01 Sep and

05 Sep, and was otherwise at quiet levels. 

Forecast of Solar and Geomagnetic Activity

07 September - 03 October 2026

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

moderate levels and a slight chance for high levels throughout the

forecast 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 09-12 Sep, 16-23 Sep, and 27 Sep-03

Oct. Levels are expected to be at normal to moderate levels on 07-08

Sep, 13-15 Sep, and 24-26 Sep. 

Geomagnetic field activity is expected to reach active to G1 storming

levels on 07-08 Sep due to the anticipated arrivals of the CMEs

discussed above. G1 storming levels are again anticipated on 24-26

Sep due to a recurrent positive polarity coronal hole high-speed

stream (CH HSS), with active levels anticipated on 27 Sep. Active

levels are also anticipated on 14-16 Sep due to a recurrent negative

polarity CH HSS. Largely quiet levels are anticipated for all

remaining dates in the forecast period.

U.K. Propagation Update-August 28, 2026

 

RSGB

RadCom Assistant Editor | August 28, 2026 Compiled by G0KYA, G3YLA and G4BAO on 27 August 2026.

Last week, we said there were no coronal holes to threaten HF propagation. However, guess what appeared just after the time of writing…

Coronal holes can appear at any time, which is why we recommend going to solarham.com  for daily updates.

This week, another coronal hole has appeared and this one really does look like it could threaten Earth. This, coupled with coronal mass ejections, means that today, 30 August, could see the Kp index rise and maximum useable frequencies, or MUFs, fall.

On a brighter note, the Kp index has been very low this past week, mostly below 2, with the result that HF propagation has been very good.

Top DX being worked includes RI1FJL on Franz Josef Land in the Arctic Circle, which has been loud on many bands, right up to the 12m and 10m bands.

Other DX to be worked in the coming week includes V5/HB9BFM from Namibia; J38DX and J38LD from Grenada and P29YY working from Papua New Guinea.

A quick check of the NCDXF beacon chain revealed very good propagation on 14MHz and 21MHz. This includes reception of the following beacons: 

CS3B in Madeira; RR90 in Siberia; 4S7B in Sri Lanka; 4X6TU in Israel; 4U1UN in New York.

So it looks like we are starting to leave the summer doldrums and entering better autumnal HF conditions.

Next week, NOAA predicts that the solar flux index will be around 120, falling to 90 as the week progresses. After the potential for geomagnetic disruption this weekend, ending today 30 August, the forecast is good with a Kp index of around 2.

VHF and up propagation news:

The weather has changed to autumnal conditions, with lows bringing periods of rain or showers and quite windy conditions at times.

The coming week will turn out in similar fashion and means that we won’t be dealing with much, if any, tropo for VHF. The main weather-dependent mode will be rain scatter for GHz band operators.

The chances of aurora will need to show a Kp index above 5 to be of much interest and probably a bit higher for southern areas.

The prospects for meteor scatter are likely to be reduced to random activity which tends to give better results in the early morning hours before dawn.

Lastly, we are coming to the close of the Sporadic-E season and, with probably a week or so to play out, any openings will be few and far between.

Try checking during the main operating windows of mid-morning and late afternoon. As a back-up, consider the middle of the day since towards the edges of the season the traditional timings are less reliable.

For EME operators, Moon declination went positive again yesterday, 29 August, with increasing peak elevation and lengthening Moon windows.

Path losses are falling all week towards perigee on Sunday, 6 September. 

144MHz sky noise is low, increasing to medium by Friday, 4 September.

Highlights of Solar and Geomagnetic Activity 17 - 23 August 2026

Solar activity reached moderate levels on 19, 20 and 21 Aug and was

at low levels on 17, 18, 22, and 23 Aug. Region 4513 (N04, L=50,

class/area Ekc/260 on 22 Aug) was the main contributor of M-class

flares, producing four out of the five M-flares observed. The

largest, an M8.1/Sf flare that peaked at 20/1142 UTC, had an

associated Type II radio sweep (estimated speed of 1201 km/s) and a

non-Earth-directed CME. Region 4513 also produced an M1.0 flare at

19/1824 UTC, an M1.8/Sf flare at 20/0805 UTC, and an M2.9/Sf flare

at 20/1611 UTC, as well as multiple C-class flares. Region 4507

(N04, L=197, class/area Ehi/300 on 18 Aug) added an M1.6 flare at

21/1017 UTC and multiple C-class flares as well.<o:p></o:p></span> 

Although proton levels never reached the S1 (Minor) storm threshold,

the greater than 10 MeV flux levels at geosynchronous orbit were

slightly enhanced between 3-6 pfu on 17-23 Aug. This enhancement was

likely associated with an energetic event from at or just beyond the

western limb on 21 Aug.<o:p></o:p></span> 

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

normal to moderate levels on 17-20 and 23 Aug, and reached high

levels on 21-22 Aug. <o:p></o:p></span> 

Geomagnetic field activity was at quiet to active levels on 17 Aug,

reached G1 (Minor) storm levels on 18-19 Aug, quiet to unsettled on

20-21 Aug, and returned to quiet levels on 22-23 Aug. The elevated

conditions on 17-19 Aug were attributed to the flanking influence

from a CME that left the Sun on 14 Aug, combined with the onset of a

CIR ahead of a negative polarity CH HSS. The slightly elevated

activity continued on 20-21 Aug as influence from the negative

polarity CH HSS persisted, and then decreased by 22-23

Aug.<o:p></o:p></span> 

Forecast of Solar and Geomagnetic Activity 24 August - 19 September 2026

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

M-class flares (R1/R2-Minor/Moderate) and a slight chance for

X-class (R3-Strong) flares on 24 Aug - 03 Sep, mainly attributed to

the flare activity and magnetic complexity of Region 4513. Activity

is then likely to decrease to just a slight chance for M-class

flares (R1/R2-Minor/Moderate) from 04 Sep - 19 Sep. 

There is a slight chance for a greater than 10 MeV proton event on

24 Aug - 03 Sep, mainly attributed to the magnetic complexity of

Region 4513. No proton events are expected from 04 Sep - 19 Sep. 

The greater than 2 MeV electron flux at geosynchronous orbit is

expected to be at high levels on 24-27 and 30 Aug, and then again on

16-18 Sep. Normal to moderate levels are expected on 28-29 and 31

Aug, and then from 31 Aug- 15 Sep and 19 Sep, 

Geomagnetic field activity is expected to be quiet to unsettled

throughout the entire period, with a chance for active conditions on 28

Aug, and 13-14 Sep, all attributed to coronal hole high-speed stream

influence.

Highlights of Solar and Geomagnetic Activity 18 - 24 May 2026

Solar activity ranged from low to moderate levels. The largest flare was an M2.3 (R1-Minor) at 22/1029 UTC from Region 4436 (N18, L=333, class/area Dai/200 on 13 May). The region was also responsible for a C8.3 and C9.5 flares on 21/1814 UTC and 21/1825 UTC, respectively. This region was then responsible for the majority of the C-class activity until its rotation off the W limb on 21 May. On 23-24 May, the majority of the C-class activity occurred from Region 4446 (S13, L=141, class/area Dko/280 on 24 May). No Earth-directed CMEs were observed during the period. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 18-24 May due to CH HSS influences. The highest flux observed was 6,667 pfu at 18/1435 UTC. 

Geomagnetic field activity ranged from quiet to active levels. Solar wind parameters began the period in a slow decline from 560 km/s as negative polarity CH HSS effects gradually diminished. At 19/0630 UTC, a small shock was observed increasing total field to 7-8 nT while solar wind speed increased to near 625 km/s before beginning to decline once again. This was likely the glancing effects from a CME that left the Sun on 16 May. Solar wind speed continued to decrease to nominal levels through 22 May. The geomagnetic field reacted with quiet to active levels on 19 May. Quiet to unsettled levels were observed on 18 May and 20-22 May. Quiet conditions occurred on 23-24 May. 

Forecast of Solar and Geomagnetic Activity 25 May - 20 June 2026

Solar activity is expected to be at low to moderate levels (R1-R2, Minor-Moderate) on 25 May through 07 Jun with the return of old Region 4432 (N14, L=081). Mostly low levels with a chance for M-class flares is expected from 08-20 Jun. 

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 25-27 May and 12-20 Jun due to CH HSS influences. 

Geomagnetic field activity is expected to be at unsettled to active levels on 27-29 May, 04 Jun, 09 Jun, and 11-15 Jun due to recurrent CH HSS activity. G2 (Moderate) storm conditions are likely on 11 Jun

and G1 (Minor) storming on 12 Jun due to CIR/CH HSS onset.

Highlights of Solar and Geomagnetic Activity 11 - 17 May 2026

Solar activity reached moderate levels on 16 May due to four M-class flares. The largest were an M1.9/2N (R1-Minor) at 16/1612UTC from Region 4436 (N18, L=330, class/area=Dao/200 on 11 May) and a second

M1.9 flare (R1-Moderate) at 16/1742UTC from Region 4435 (N22, L=040, class/area=Dao/070 on 15 May). The 1612UTC M1.9 was associated with a Type IV radio sweep, two 10.7 cm radio bursts, and a filament

eruption that was centered at approximately N21W07, which lead to a complex CME signature in coronagraph imagery. The first front was first seen in LASCO C2 imagery at 16/1636UTC, and the second front

became visible at approximately 16/1700 UTC. Analysis and modeling of the event suggests potential for a glancing blow at Earth by mid UTC-day on 18 May, with the bulk of the material passing northward

of Earth&#39;s orbit. 

The other two M-flares, an M1.4 at 17/0339UTC and an M1.3 at 16/1629, were also from Regions 4435 and 4436, with the M1.3 following on the heels of the 16/1612UTC M1.9. The other 11 numbered

active regions on this visible disk were either quiet or only produced C-class activity during the past week. 3 Type II radio sweeps and an additional 10.7cm radio burst were observed during the

summary period, but they were not associated with any Earth-directed activity 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels for the majority of the summary period, before increasing to high levels at 16/1740UTC. During the summary

period, the maximum value reached was 6,120 pfu at 17/1740UTC. 

Geomagnetic field activity reached G1-G2 (Minor-Moderate) geomagnetic storm levels on 15-16 May due to a negative polarity coronal hole high-speed stream becoming geoeffective late on 15 May.

Total magnetic field strength, Bt, increased all throughout 15 May, from approximately 3 nT to a peak of 17 nT at 15/1555UTC. The north-south component, Bz, rotated between +/- 11 nT, with maximum

southward deflections of approximately -13 nT. The interplanetary magnetic field had returned to background levels by the end of 16 May. A smaller positive polarity coronal hole high speed stream

became geoeffective on 13 May with a max Bt of 13 nT and maximum Bz southward deflection of -9 nT; however this only produced unsettled geomagnetic conditions and no NOAA Geomagnetic Storming thresholds

were reached. 

Forecast of Solar and Geomagnetic Activity 18 May - 13 June 2026

Solar activity is expected to be at low to moderate levels throughout the outlook period, with M-class activity (R1-R2, Minor-Moderate) ranging from a chance to likely and X-class activity (R3, Strong) ranging from a slight chance to a chance, due to the flare potential of several active regions currently on the visible disk and those both expected to return and indicated by Solar Orbiter magnetic imagery. 

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 18 May and 21-23 May due to the influence from the current negative polarity coronal hole high-speed stream and an anticipated solar sector boundary cross on 21 May. The remaining days of the outlook period are likely to be at normal to moderate levels. 

Geomagnetic field activity is expected to reach G1 (Minor) geomagnetic storm levels over 18-19 May due to potential influences from the CME that left the Sun on 16 May, arriving in the near-Earth environment in the midst of the current high-speed stream. The remainder of the outlook period is anticipated to be at largely quiet to unsettled levels.

Highlights of Solar and Geomagnetic Activity 16 - 22 February 2026

Solar activity ranged from very low to moderate levels. The largest event was an M2.5 flare (R1-Minor) at 16/0435 UTC from a location beyond the east limb. A Type II radio sweep (est. 310 km/s) was observed on 18 Feb and associated with a large eruption just beyond the southeast limb. Only low-levels C-class activity was observed over 17-23 Feb. The sun ended the summary period free of sunspots on the visible disk for the first time since 2022. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels over 16-20 Feb following sustained higher wind speeds from a positive polarity coronal hole. Normal to moderate levels were observed over 21-22 Feb. 

Geomagnetic field activity reached a peak of G2 (Moderate) levels on 16 Feb due to influence from a positive polarity CH HSS. Quiet to unsettled levels were observed over 17-19 Feb. Active levels over 20-21 Feb were likely associated with transient passage. By 22 Feb,a CIR ahead of a negative polarity CH HSS increased geomagnetic conditions up to G1 (Minor) geomagnetic storm levels. Wind speeds were observed between 600-700 km/s on 22 Feb as the high speed stream set in. 

Forecast of Solar and Geomagnetic Activity 23 February - 21 March 2026

Solar activity is expected to be at very low, with a good change for C-class flares and a slight change for M-class flare (R1/R2-Minor/Moderate) 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 23 Feb - 03 Mar, 06-08 Mar, 11-12 Mar, 15-19 Mar, and 21 Mar due to anticipated influence of multiple recurrent coronal holes. The remainder of the outlook period is likely to be at normal to moderate levels. 

Geomagnetic field activity is expected to reach G2 (Moderate) levels on 21 Mar.;G1 (Minor) geomagnetic storm levels are likely on 23 Feb, 10 Mar, 14 Mar, and 20 Mar; active levels are likely on 24 Feb, 05-06 Mar, 12-13 Mar, 15-16 Mar, and 19 Mar; unsettled levels are likely over 25 Feb, 07 Mar, 09 Mar, 11 Mar, and 17-18 Mar. All increases in geomagnetic activity are anticipated due to expected 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 29 December - 04 January 2026

Solar activity ranged from low to high levels. High levels were observed on 31 Dec following an M7.1/1N flare at 31/1351 UTC from Region 4324 (N25, L=288, class/area=Dao/230 on 29 Dec). Associated with the event was Type IV and Type II radio sweeps, a Tenflare, and a CME signature to the NE in subsequent coronagraph imagery.

Modeling of the CME event suggested passage by Earth late on 03 Jan. Moderate levels were observed on 01 Jan following an M1/Sf flare at 29/0651 from Region 4325 (S08, L=296, class/area=Eki/330 on 01 Jan). The other 21 numbered active regions across the visible disk this week were either quiet or only produced C-class activity. A Type II radio sweep was reported on 02 Jan but was associated with a CME that erupted from beyond the W limb. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels over the past seven days. 

Geomagnetic field activity was mostly at quiet to unsettled levels on day, but 02 Jan. G1 (Minor) geomagnetic storm levels were observed on late on 02 Jan, following the arrival of the last of a set of weak CMEs that left the Sun over 28-31 Dec. Total magnetic

field strength reached a peak of 09 nT as the CME passed. Bz reached as far south as -8 nT. Solar wind speeds peaked between ~600-700 km/s. While influence from a negative polarity coronal hole was observed beginning on 31 Dec, no significant geomagnetic activity was observed from the feature over the following days. 

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

Solar activity is likely to remain at low levels, with a chance for moderate (R1-Minor) conditions and a slight chance for high (R2/R3-Moderate-Strong) over the next solar rotation due to multiple regions on the visible disk as well as regions expected to return from the Sun&#39;s farside. 

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 05 Jan and 15 Jan - 13 Jan due to the anticipated influence of multiple, recurrent coronal holes. The remainder of the outlook period is likely to at normal to moderate levels. 

Geomagnetic field activity is likely to reach G1 (Minor) geomagnetic storm levels on 13-14 Jan, 17-20 Jan, and 29 Jan; active levels are likely on 05 Jan and 28 Jan; unsettled levels are likely on 09-10 Jan, 12 Jan, 21-22 Jan, 27 Jan, and 30-31 Jan. All enhancements in geomagnetic activity are due to the anticipated influence of

multiple, recurrent, coronal holes. The remainder of the outlook period is expected to be mostly quiet.
