Bulletin

Six sunspot groups are reported by NOAA today. The most active of them is NOAA AR 2036 (no Catania number yet) that produced five low C-class flares today. However, the strongest flares of today (C7.5 peaking at 04:38 UT and C5.2 peaking at 08:00 UT) are produced by a still unnumbered sunspot group that just appeared from behind the south-east solar limb. We expect further flaring activity on the C-level from these two groups, with a good chance for an M-class event in the active region at the south-east limb. The Earth is currently inside a slow (around 380 km/s) solar wind flow with average (5-6 nT) interplanetary magnetic field magnitude. The geomagnetic conditions are quiet and are expected to remain so.

Today's estimated international sunspot number (ISN): 080, based on 17 stations.
