Bulletin

Five sunspot groups were reported by NOAA today, but only high B-class flares were detected in the past 24 hours. The NOAA AR 2497 has grown in the number of spots and developed beta-gamma configuration of its photospheric magnetic field, so it can be expected to produce flaring activity on the C-level. The Earth is currently inside a slow (around 360 km/s) solar wind flow with weak to average (around 4 nT) interplanetary magnetic field magnitude. The geomagnetic conditions are quiet and are expected to remain so.

Today's estimated international sunspot number (ISN): 084, based on 09 stations.
