Only C-class flares occurred in past 24h. The strongest one was a C3.4 from NOAA AR 1750 with peak at 09:15 UT. NOAA AR 1748 has lost complexity and has now a beta-delta magnetic configuration, it still can produce M flares and, less likely, X-class flares. The 10 MeV proton flux has descended below the threshold of 10 protons/cm2-s-sr, for the first time since May 15. Geomagnetic activity has ranged from unsettled to active in past 24h. It can reach up to major storm levels when the May 17 CME arrives to the Earth today.
Today's estimated international sunspot number (ISN): 087, based on 12 stations.
