Bulletin

Seven sunspot groups were reported by NOAA today. Three more groups still have no NOAA numbers. Two of these unnumbered groups rapidly emerged yesterday in the SW and SE quadrants of the Sun, and another group appeared from behind the east solar limb. No flares were observed in any of the unnumbered groups yet, although the dynamic sunspot group in the SE quadrant may become flare-productive. All the flares in the past 24 hours occurred in the NOAA AR 1959, the strongest of them being the C3.4 flare peaking at 02:20 UT today. We expect further flaring activity on the C-level, with M-class flares possible but unlikely. The Earth is currently inside a slow (around 300 km/s) solar wind flow with weak to average (3-4 nT) interplanetary magnetic field magnitude. We expect quiet geomagnetic conditions in the coming hours. Tomorrow we expect the arrival of a fast flow from a low-latitiude coronal hole in the northern hemisphere. Active geomagnetic conditions will be possible.

Today's estimated international sunspot number (ISN): 104, based on 06 stations.
