Highlights of Solar and Geomagnetic Activity
10 - 16 February 2025
Solar activity reached moderate levels on 10-11 and 13-14 Feb, with
low levels of activity observed on 12 and 15-16 Feb. In total, six
M1 flares (R1-Minor) were observed throughout the week from Regions
3981 (N07, L=341, class/area=Esi/190 on 10 Feb), 3990 (S10, L=191,
class/area=Dki/310 on 14 Feb), and 3992 (S06, L=243,
class/area=Dai/210 on 13 Feb).
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at
normal to moderate levels on 10 Feb, with high levels observed on
11-16 Feb.
Geomagnetic field activity reached G1 (Minor) levels on 10 and 14-15
Feb, and active levels on 11-13 and 16 Feb, due to negative polarity
CH HSS influences.
Forecast of Solar and Geomagnetic Activity
17 February - 15 March 2025
Solar activity is expected to range from low to moderate levels
throughout the period. There is a varying chance for R1-R2
(Minor-Moderate) events, and a slight chance for R3 or greater
events.
No proton events are expected at geosynchronous orbit, barring
significant flare activity.
The greater than 2 MeV electron flux at geosynchronous orbit is
likely to reach high levels on 18-19 and 23 Feb, and 10-15 Mar.
Normal to moderate levels are likely to prevail throughout the
remainder of the period.
Geomagnetic field activity is likely to reach G1 (Minor) levels on
28 Feb, 09 and 12-14 Mar, with active levels likely on 17-18 Feb,
and on 01 and 15 Mar, due primarily to CH HSS influences. Quiet and
quiet to unsettled conditions are expected to prevail throughout the
remainder of the period.
