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.
