Forecast of Solar and Geomagnetic Activity
09 February - 07 March 2026

Solar activity is expected to continue at moderate levels with
further M-class (R1-R2, Minor-Moderate) flares expected and a chance
for X-class (R3-Strong or greater) on 09-10 Feb as Region 4366
transits the western limb. Low levels, with a chance for M-class
flares, are expected on 11-22 Feb. An increase to moderate to high
levels is once again likely on 23-28 Feb as Region 4366 returns to
the visible disk. Conditions should again return to low to moderate
levels on 01-07 Mar as old Region 4366 rotates to the far side once
again.

There is a chance for the 10 MeV proton flux to reach S1-S2
(Minor-Moderate) storm levels through 12 Feb as Region 4366 transits
the visible disk and beyond. Levels are likely to be below the S1
(Minor) level on 12-22 Feb. An increase to above the S1 (Minor)
storm levels 23-28 Feb is possible as Region 4366 returns to the
visible disk. Chances decrease on 01-07 Mar as old Region 4366
rotates to the far side once again.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at high levels on 09-10 Feb, 16-21 Feb, 24-25 Feb,
and 05-07 Mar as CH HSS influence sporadically continue.

Geomagnetic field activity is expected to be at unsettled to active
levels on 09-10 Feb as CH HSS influence decreases. Barring the
potential for CME activity, mostly quiet to unsettled levels are
expected from 11-15 Feb, 22-23 Feb, and 26 Feb - 04 Mar. Unsettled
to active levels are likely on 16-21 Feb, 24-25 Feb, and 05-07 Mar
due to recurrent negative polarity CH HSS effects.
