NOAA AR 2235 has decayed, so solar activity has been led by NOAA AR 2239. It produced several C-class flares in past 24 h. the strongest being a C5.5 with peak at 04:09 UT. M-class flares are possible. The solar wind is at nominal levels (speed 400 km/s, magnetic field magnitude 5 nT). Geomagnetic conditions are quiet and expected to remain so.

Today's estimated international sunspot number (ISN): 105, based on 15 stations.
