Forecast of Solar and Geomagnetic Activity
02 June - 28 June 2025

Solar activity is likely to reach moderate levels
(R1-R2/Minor-Moderate), with a chance for R3 (Strong), through 06
Jun as Region 4100 makes it to the west limb. A chance for M-class
(R1-R2) X-ray activity will persist throughout the outlook period
due to multiple regions on the visible as well as multiple active
regions scheduled to return from the farside of the Sun.

The current proton event in progress is expected to end on 02 Jun
with no additional events expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at high levels on 03-05, 14-22 and 26-28 Jun
following recurrent coronal hole influence. The remainder of the
period is expected to be at normal to moderate levels.

Geomagnetic field activity is expected to be at mostly elevated
levels due to anticipated influence from miltiple, recurrent coronal
holes. G1 (Minor) to G2 (Moderate) geomagnetic storms are likely on
02-03 Jun due to waning CME effects. Unsettled to active conditions
are likely on 04-07 and 10-12 Jun due to recurrent negative polarity
CH HSS influence. Unsettled to G1 (Minor) conditions are likely on
13-22 Jun due to positive polarity CH HSS influence. Unsettled to G1
(Minor) conditions are likely on 23-28 Jun due to negative polarity
CH HSS influence.
