Highlights of Solar and Geomagnetic Activity
16 - 22 June 2025

Solar activity reached high levels on 17 and 19 Jun when Region 4114
(N21, L=35, class/area=Ekc/400 on 19 Jun), the largest and most
complex region on the disk throughout the week, produced an X1.2/2b
flare at 17/2149 UTC and an X1.9 flare at 19/2350 UTC; the strongest
events observed this period. In addition, Region 4114 produced five
R1 (Minor) events on 16-17 and 20 Jun, and one R2 (Moderate) event
on 16 Jun. Region 4117 (S14, L=303, class/area=210 on 19 Jun)
produced a single R1 (Minor) event this period; an M1.0/1f flare at
20/1740 UTC. No Earth-directed CMEs were observed throughout the
week.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
normal to moderate levels throughout the period.

Geomagnetic field activity was at quiet to active levels on 16,
18-19, and 21-22 Jun, with quiet to unsettled levels observed on 17
and 20 Jun, due to sustained positive polarity CH HSS influences
throughout the week. No Earth-directed CMEs were detected in solar
wind data.
