Forecast of Solar and Geomagnetic Activity
01 June - 27 June 2026

Solar activity is expected to be at predominately low levels
throughout the outlook period, with a chance for M-class
(R1-R2/Minor-Moderate) flare activity.

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 12-20 Jun, with normal to moderate
levels likely throughout the remainder of the period.

Geomagnetic field activity is likely to reach G2 (Moderate) storm
levels on 11 Jun, with G1 (Minor) storming likely on 12 Jun, due to
negative polarity CH HSS influences. Active conditions are likely on
01, 03-05, 13-14, and 23-27 Jun due to multiple recurrent CH HSSs.
Quiet and quiet to unsettled conditions are expected to prevail
throughout the remainder of the outlook period.
