A C2.1 flare peaking at 02:28UT was observed in NOAA 2524. It was associated with a small coronal mass ejection (CME) which was not directed to Earth according to currently available coronagraphic imagery. The region also produced some jets and 3 B-class flares. NOAA 2526 produced 2 B-class flares during the second half of the period. A potentially active region may round the east limb later today. The eruption of a small filament was observed in the southwest solar quadrant between 05:30 and 06:10UT. Standing-by coronagraphic imagery to assess any CMEs.
There is a chance on an isolated C-class flare.
Under the influence of the coronal hole stream, solar wind speed gradually increased from about 410 km/s at midnight to values near 500 km/s by 06:00-08:00UT. Initially, Bz varied wildly between -9 and +10 nT, whereas after midnight more steady periods were observed with Bz mostly between -5 and +7 nT. Geomagnetic conditions were quiet to unsettled, with an active interval reported in local K by Dourbes (15-18UT) and in Kp (03-06UT).
Mostly quiet to unsettled geomagnetic conditions are expected, with an active episode possible.
Today's estimated international sunspot number (ISN): 023, based on 14 stations.
