Highlights of Solar and Geomagnetic Activity 07 - 13 July 2025
Solar activity was ranged from low to moderate levels. R1 (Minor) events were observed on 08-09 Jul and 12 Jul. The largest was an M2.4 flare at 08/0417 UTC from Region 4136 (N19, L=022, class/area=Dai/220 on 11 Jul). Region 4140 (S15, L=348, class/area=Dao/130 on 12 Jul) produced a similarly powerful M2.3/1f
flare at 12/0834 UTC. The other 15 numbered active regions on the visible disk were either quiet or only produced C-class 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 09-10 Jul following elevated wind speeds from a coronal hole. The remainder of the summary period was at normal to moderate levels.
Geomagnetic field activity was varied from quiet to G1 (Minor) geomagnetic storm levels. G1 conditions were observed early on 07 Jul, with a slow decrease to active levels on 08 Jul and unsettled levels on 09 Jul due to influence from a negative polarity coronal hole. Active conditions were observed on 11 Jul and unsettled
conditions on 12 Jul were in response to the onset of a positive polarity coronal hole. G1 conditions observed on 13 Jul followed a pronounced increase in solar wind speeds from a mildly elevated ~500 km/s on 12 Jul to a peak just over 700 km/s on 13 Jul.
Forecast of Solar and Geomagnetic Activity 14 July - 09 August 2025
Solar activity is likely to be at low levels, with a chance for R1-R2 (Minor-Moderate) radio blackouts, over next 27 days due to several complex active regions on the visible disk and the anticipated return of multiple active regions 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 reach high levels on 20-28 Jul and 05-06 Aug following activity from recurrent coronal holes. The remainder of the outlook is likely to be at normal to moderate levels.
Geomagnetic field activity is likely observed mild elevations, mostly in response to recurrent coronal hole features. Active conditions are likely on 14 Jul, 22-24 Jul, 02-04 Aug, and 07-09 Aug. Unsettled conditions are likely on 15-17 Jul, 25 Jul, and 01 Aug. The remaining days of the outlook period are expected to be
mostly quiet.
