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.

Solar activity reached high levels on 17 and 19 Jun when Region 4114 (N21, L=35, class/area=Ekc/400 on 19 Jun), the largest and most complex region on the disk throughout the week, produced an X1.2/2b flare at 17/2149 UTC and an X1.9 flare at 19/2350 UTC; the strongest events observed this period. In addition, Region 4114 produced five R1 (Minor) events on 16-17 and 20 Jun, and one R2 (Moderate) event on 16 Jun. Region 4117 (S14, L=303, class/area=210 on 19 Jun) produced a single R1 (Minor) event this period; an M1.0/1f flare at 20/1740 UTC. No Earth-directed CMEs were observed throughout the week.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels throughout the period.

Geomagnetic field activity was at quiet to active levels on 16, 18-19, and 21-22 Jun, with quiet to unsettled levels observed on 17 and 20 Jun, due to sustained positive polarity CH HSS influences throughout the week. No Earth-directed CMEs were detected in solar wind data.
