Highlights of Solar and Geomagnetic Activity 03 - 09 July 2017
Solar activity ranged from very low to moderate levels. The period began on 03 Jul with an M1 flare (R1-Minor) observed at 03/1615 UTC from an emerging region on the west limb. A CME was associated with the M1 flare, but was determined to be well off the Sun-Earth line. Low levels were observed on 04 Jul due to a single C1 flare observed at 04/0425 UTC from this same unnumbered region. Very low levels were recorded on 05-06 Jul. Activity increased to low levels on 07 and 08 Jul as new Region 2665 (S06, L=111, class/area Ekc/710 on 09 Jul) produced a C1 flare observed at 07/1349 UTC. This was followed by a C3/Sf flare observed at 08/2353 UTC from the same region. Activity levels increased to moderate as developing Region 2665 produced an impulsive M1/2n flare (R1-Minor) observed at 09/0318 UTC. Additional C-class flares were observed from Region 2665 throughout the remainder of 09 Jul.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels throughout the period.
Geomagnetic field activity was at quiet to isolated unsettled levels from 03-08 Jul. During this time, the solar wind environment was at nominal levels with the phi angle in a steady negative orientation.
By early on 09 Jul, solar wind parameters reflected the onset of a CIR in advance of a recurrent, positive polarity CH HSS. The geomagnetic field responded with active to minor storm levels
(G1-Minor) throughout 09 Jul. Solar wind speed increased from near 365 km/s to a maximum of 602 km/s at 09/2103 UTC. Total field ranged from 4-14 nT while the Bz component varied between +/-11 nT. Phi angle rotated from a negative to a mostly positive sector after
09/0430 UTC.
Forecast of Solar and Geomagnetic Activity 10 July - 05 August 2017
Solar activity is expected to be at low levels throughout the outlook period. A chance for additional M-class activity (R1-R2, Minor-Moderate) is possible from 10-30 Jul.
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 10-15 Jul with normal to moderate levels expected throughout the remainder of the outlook period.
Geomagnetic field activity is expected to be at generally quiet to unsettled levels for a majority of the outlook period. Unsettled toactive conditions are likely on 10 Jul with active to minor storm
levels (G1-Minor) likely on 05 Aug due to the influence of arecurrent, positive polarity CH HSS.
