Bulletin

Solar flaring activity remained below the C-level in the past 24 hours, although several B-class flares were detected. Catania sunspot group 79 (no NOAA AR number yet) exhibited significant magnetic flux emergence with the appearance of new sunspots. Another sunspot group has just appeared from behind the north-east solar limb. A C-class flare is probable. The Earth is currently inside a slow (around 330 km/s) solar wind flow with average (around 5 nT) interplanetary magnetic field magnitude. The geomagnetic conditions are quiet and are expected to remain so.

Today's estimated international sunspot number (ISN): 035, based on 20 stations.
