The strongest events of the period were two M1 flares peaking at resp. 17:23UT and 23:38UT. Both were produced by sunspot region NOAA 2615 (S05E45), with no obvious coronal dimming observed. A small delta in the middle portion of NOAA 2615 was the cause of all the flaring. This sunspot region is still quite small, but is gradually growing and has mostly kept its relatively complex magnetic configuration. NOAA 2612 and NOAA 2614 are decaying and were quiet. No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery from SOHO and STEREO-A. The greater than 10MeV proton flux was at nominal levels.
C-class flares are expected, with a chance on another M-class event from NOAA 2615.
Solar wind parameters are at nominal levels, with the wind speed near 350 km/s and Bz fluctuating between -3 nT and +4 nT. The interplanetary magnetic field was mostly directed away from the Sun. Solar wind parameters are expected to remain at nominal values.
The geomagnetic field was at quiet levels, with a single unsettled episode at Dourbes (21-24UT). Geomagnetic activity is expected to remain at quiet levels.
Today's estimated international sunspot number (ISN): 062, based on 21 stations.
