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. 73 de VA2OM, SYSOP of VE2PKT
