Bulletin

The flaring activity during last 24 hours was of the B-class level, except M1.3 flare which peaked at 08:57 UT this morning. The flare originated from the Catania sunspot group 92 (NOAA AR 1762) which still has beta-gama configuration of its photosperic magnetic field and has therefore potential for a C-class and M-class flaring. The flare was associated with a partial halo CME first seen in the SOHO/LASCO C2 field of view at 09:12 UT (this is also the first image after the data gap), and propagating with the projected speed of about 300 km/s. From the currently available data it seems that the bulk of the CME mass was southward oriented. We do not expect this CME to arrive at the Earth, however the arrival of the CME associated shock wave is still possible. The interplanetary magnetic field magnitude is about 4 nT. The solar wind speed is currently about 500 km/s and is still slowly decreasing. The equatorial coronal hole passed the central meridian today, however not much impact is expected from this small coronal hole. The geomagnetic conditions are unsettled to quiet (Dourbes reports K=3 or less), and expect to remain so in the following hours.

Today's estimated international sunspot number (ISN): 054, based on 19 stations.
