Forecast of Solar and Geomagnetic Activity
30 June - 26 July 2025

Solar activity is expected to be at low levels on 30 Jun - 04 Jul.
Moderate (R1-R2, Minor-Moderate) levels are likely on 05 Jul - 26
Jul with the return of old Regions 4114 (N21, L=035) and 4117 on 05
Jul and 12 Jul, respectively.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach high levels on 30 Jun -01 Jul, 03 -08 Jul, and
again on 20-26 Jul due to recurrent CH HSS influence.

Geomagnetic field activity is expected to reach unsettled to active
levels with G1 (Minor) geomagnetic storming likely on 02-03 Jul with
the arrival of the 28 Jun CME. Unsettled to active levels are
expected on 04-09, 11-19, 22-25 Jul with G1 (Minor) storming likely
on 23-24 Jul due to recurrent CH HSS activity.
