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. Forecast of Solar and Geomagnetic Activity 23 June - 19 July 2025 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. 73 de VA2OM, SYSOP of VE2PKT
