Highlights of Solar and Geomagnetic Activity
05 - 11 May 2025

Solar activity reached moderate levels in the final minutes of 11
May following an M-class event that peaked after the turn of the UT
day. Solar activty was low the remainder of the time (05-10 May)
leading up to that event. Region 4079 (N08, L=240,
class/area=Ekc/1250 on 06 May) was responsible for what ended up
being an M1.9 flare that peaked at 12/0001 UTC. This region was also
responsible for 54 C-class events during the week, most of which
were sub C5 level. Region 4082 (S11, L=180, class/area=Dac/140 on 06
May) contributed a pair of C7.0 flares at 08/1141 and 08/1500 UTC
respectively, as well as several other low level C-class flares. No
significant Earth-directed CMEs were noted during the period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
high levels on 06-09 May, and moderate levels on 10-11 May.

Geomagnetic field activity was at quiet to unsettled levels on 07
May, quiet to active levels on 06 and 08-10 May, and active to minor
storm levels on 05 and 11 May. The increased activity was likely
associated with negative polarity CH HSS influence.
