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.
Forecast of Solar and Geomagnetic Activity
23 June - 19 July 2025
Solar activity is expected to range from low to moderate levels
throughout the period. There is a chance for R1-R2 (Minor-Moderate)
radio blackouts, and a slight chance for R3 (Strong) or greater
events, through 18 Jul.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
likely to reach high levels on 26-28 Jun, with normal to moderate
levels likely to prevail throughout the remainder of the period.
Geomagnetic field activity is likely to reach G1 (Minor) storm
levels on 25-26 Jun, and active levels on 24 and 27 Jun and 01-03,
05-06, and 11-12 Jul, all due to recurrent CH HSS influences. Quiet
and quiet to unsettled conditions are expected to prevail throughout
the remainder of the period.
