=================================== Weekly Space Weather Highlights =================================== Highlights of Solar and Geomagnetic Activity 29 May - 04 June 2023 Solar activity was high. There were a total of seven M-class flares during the period. The largest event was an M4.2/Sf flare (R1-Minor) from Region 3323 (S07, L=100, class/area = Ehi/320 on 04 June). Regions 3310 (S20, L=284, class/area = Cho/480 on 24 May), 3315 (S16, L=233, class/area = Ekc/630 on 29 May), 3319 (S19, L=199, class/area = Dhi/300 on 31 May), and 3324 (N15, L=159, class/area = Bxo/20 on 02 June) also produced M-class flaring below the M5 level. The remaining numbered active regions on the visible disk were either quiet or only produced C-class events. No proton events were observed at geosynchronous orbit. The greater than 2 MeV electron flux at geosynchronous orbit reached moderate levels each day of the highlight period. Geomagnetic field activity ranged from quiet to active levels. Active levels were reached on 01 and 04 June, with unsettled conditions observed on 31 May as a result of recurrent CH HSS influence. Quiet levels were reported for the remainder of the period. Forecast of Solar and Geomagnetic Activity 05 June - 01 July 2023 Solar activity is likely to be at low to moderate levels (R1-R2, Minor-Moderate) throughout the outlook period, due to several complex regions currently on the visible disk and the anticipated return of several regions that have produced moderate level activity currently on the farside of the Sun. 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 05-10 and 19-24 June in response to elevated wind speeds from multiple, recurrent CH HSSs. The remainder of the outlook period is anticipated to be at moderate levels. Geomagnetic field activity is expected to range from quiet to G1 (Minor) geomagnetic storm levels. G1 conditions are likely on 18 June; active levels are likely on 12,19-20, and 28 June; unsettled conditions are likely on 05-06, 11, 13, 21, 27 June and 01 July due to recurrent CH HSS influence. Quiet conditions are expected for the remainder of the outlook period.
