Highlights of Solar and Geomagnetic Activity
28 April - 04 May 2025
Solar activity reached moderate levels on 29 and 30 Apr due to
M-Class flare activity. Region 4078 (N16, L=009, class/area=Cro/20
on 29 Apr) produced an M1.3/1N flare at 29/1002 UTC and an M1.6/1N
flare at 29/1057 UTC. Region 4079 (N07, L=242, class/area=Ekc/1210
on 02 May) produced an M1.7 flare at 29/0513 UTC and an M2.0 flare
at 30/0751 UTC, the largest of the period. Low levels were obsereved
throughout the remainder of the period. No Earth-directed CME
resulted from this week's flare activity.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at
moderate levels on 28 Apr - 01 May, and reached high levels on 02-04
May.
Geomagnetic field activity was at quiet to unsettled levels on 28-29
Apr. Activity increased to active levels on 30 Apr, and reached G1
(Minor) levels on 01-05 May due to negative polarity coronal hole
influence.
Forecast of Solar and Geomagnetic Activity
05 May - 31 May 2025
Solar activity is expected to be predominently low through the
outlook period, with a varying chance for M-class flare activity.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
likely to reach high levels from 05-12 May and 29-31 May. Normal to
moderate levels are expected from 13-28 May.
Geomagnetic field activity is likely to reach G1 (Minor) storm
levels on 18 May and 29-31 May due to negative polarity coronal hole
influence. Periods of active conditions are likely on 05-06 May,
09-11 May, 16-17 May, 19-21 May, and 27 May in response to CH HSS
incluences. Quiet to unsettled conditions are expected to prevail
throughout the remainder of the period.
