Forecast of Solar and Geomagnetic Activity
08 June - 04 July 2026

Solar activity is expected to be at predominately low levels through
04 Jul, with M-class flare probabilities ranging from a chance to
likely levels throughout the period.

No proton events are expected at geosynchronous orbit, barring
significant flare activity.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach high levels on 09-10, 13-18 Jun and 04 Jul. Normal
to moderate levels are expected to prevail throughout the remainder
of the period.

Geomagnetic field activity is likely to reach G1-G3 (Minor-Strong)
storm levels on 08 Jun, with G1-G2 (Minor-Moderate) levels likely on
09 Jun, due to the anticipated arrival of the CME that left the Sun
on 06 Jun. Periods of active conditions are likely on 23-26 Jun due
to recurrent CH HSS influences. Quiet and quiet to unsettled levels
are expected to prevail throughout the remainder of the period.
