Forecast of Solar and Geomagnetic Activity
10 November - 06 December 2025

Solar activity is likely to be at moderate levels (R1-Minor), with a
chance for high (R2-R3/Moderate-Strong), over 10-18 Nov, primarily
due to the flare potential from Regions 4274 and 4276. The remainder
of the outlook period is likely to be at low levels, with a chance
for moderate activity.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at high levels over 10-13 Nov following a combination
of CME and coronal hole influence. High levels are again likely on
27 Nov-02 Dec due to influence from a recurrent, positive polarity
CH HSS. The remainder of the outlook period is likely to be at
normal to moderate levels.

Geomagnetic field activity is expected to range from quiet to G2
(Moderate) geomagnetic storm levels. G1 (Minor) conditions are
likely on 11 Nov due to anticipated influence from both a negative
polarity coronal hole and a CME that left the Sun 07 Nov. G2
conditions are likely on 11-12 Nov due to anticipated influence from
CMEs that left the Sun on 09 Nov. Unsettled conditions are likely
over 13 Nov as CME influence wanes. Recurrent coronal hole influence
is likely to cause G1 conditions over 25-27 Nov and 02-04 Dec;
active condition on 20 Nov, 24 Nov, 29-30 Nov, and 05 Dec; unsettled
conditions on 16 Nov, 21 Nov, 28 Nov, 01 Dec, and 06 Dec. The
remainder of the outlook period is likely to be at mostly quiet
levels.
