Highlights of Solar and Geomagnetic Activity
07 - 13 April 2025

Solar activity was at high levels on 12-13 April due to the rapid
growth and complexity of Region 4055 (N07 L=235, class/area Ekc/820
on 13 April). This region totalled 19 M-class flares during the
highlight period. The largest was an M3.2 flare at 1851 UTC on 13
April. Region 4048 (S16 L=279, class/area Fkc/460 on 07 April)
produced M-class activity as well. Other highlights included
filament activity in the south central portion of the disk. Two
filament eruptions were observed. The first was approximately 20
degrees long, centered near S20E20, and began erupting after
~12/2130 UTC. The second filament was approximately 12 degrees long,
centered near S22W09, and began erupting after ~13/0500 UTC. CME
signatures were observed in subsequent coronagraph imagery following
each event. Initial analysis and modeling indicated a likely
Earth-directed component, with anticipated arrival at Earth near
midday on 16 Apr.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
moderate to high levels on 07-13 Apr due to the influence of various
CH HSSs.

Geomagnetic field activity reached G1 (Minor) storm levels on 08-09,
and 12 April all due to influences from CH HSSs. Unsettled to active
levels were observed on the remaining days in the highlight period.
