Bulletin

Nine sunspot groups were reported by Catania today. Catania sunspot group 25 (NOAA AR 2036) was responsible for the most of the flaring activity during the past 24 hours. The strongest flare of this period, however, was produced by the Catania sunspot group 24 (NOAA AR 2035) that showed rapid magnetic flux emergence in the past several hours: the C8.6 flare peaking at 09:23 UT. We expect further flaring activity on the C-level from these two active regions, with a good chance for an M-class event. The Earth is currently inside a slow (around 350 km/s) solar wind flow with weak (2-3 nT) interplanetary magnetic field magnitude. The geomagnetic conditions are quiet and are expected to remain so.

Today's estimated international sunspot number (ISN): 102, based on 22 stations.
