Forecast of Solar and Geomagnetic Activity
31 March - 26 April 2025

Solar activity will continue at a chance for R1-R2 (Minor-Moderate)
throughout the outlook period due to multiple complex regions on the
visible disk as well as on the Sun's farside that are likely to
return. A slight chance exists for R3 (Strong) events over the next
three days primarily due to the flare potential from complex regions
in the Sun's eastern hemisphere.

No proton events are expected at geosynchronous orbit are likely to
remain below the S1 (Minor) solar radiation storm threshold (>10
MeV proton flux of 10 pfu).

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at high levels on 31 Mar, 06-14 Apr, and 23-26 Apr in
response to multiple, recurrent, CH HSSs. The remainder of the
outlook period is expected to be at normal to moderate levels.

Geomagnetic field activity is expected to range from quiet to G2
(Moderate) geomagnetic storm conditions. G2 conditions are likely on
05 Apr and 09 Apr; G1 (Minor) conditions are likely over 04 Apr, 08
Apr, and 10 Apr, active conditions are likely over 11 Apr, 13 Apr,
and 21-24 Apr; unsettled conditions are likely on 03 Apr, 06-07 Apr,
12 Apr, 14-15 Apr, 17-20 Apr, and 25-26 Apr. All increases in
geomagnetic activity are anticipated in response to multiple,
recurrent, CH HSSs. The remainder of the outlook period is likely to
mostly quiet.
