Highlights of Solar and Geomagnetic Activity
14 - 20 April 2025

Solar activity reached moderate levels due to M-class flare activity
on 14-15, 18 and 20 Apr. The largest event of the period was an M4.4
flare at 18/2350 UTC from an unseen source beyond the SE limb. No
Earth-directed CMEs resulted from this week's solar activity.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels on 14 Apr, with normal to moderate levels observed over
15-20 Apr.

Geomagnetic field activity began the period at quiet to active
levels in response to negative polarity CH HSS influences on 14 Apr.
Periods of G1-G2 (Minor-Moderate) storming was observed on 15 Apr,
with periods of G1-G4 (Minor-Severe) storming observed on 16 Apr,
due to the passage of a CME that left the Sun on 13 Apr. Remnant CME
influences and bouts of southward IMF persisted on 17-18 Apr with
quiet to active levels observed. Quiet to active levels were
observed on 19 Apr, and quiet to G1 (Minor) levels were observed on
20 Apr, in response to prolonged periods of southward Bz.
