Bulletin

Solar activity continues to be low with only 3 C-class flares reported in the last 24 hours. The strongest flare was C1.5 flare, peaking at 05:54 UT this morning. The majority of the flaring activity originated from the Catania sunspot group 13 (NOAA AR 2305) which is growing in size and in number of sunspots. Since this sunspot group also maintains beta- gamma configuration of its photospheric magnetic field, it is the most probable source of the C-class flares expected in the coming hours. No Earth directed CMEs were observed during last 24 hours. The solar wind speed is slowly decreasing and it currently amounts about 550 km/s. The interplanetary magnetic field is stable having the magnitude of about 5 nT. The geomagnetic conditions are quiet as reported by Izmiran (K=2) and NOAA (Kp=2). The local station at Dourbes reported value of K=5 during one interval this morning. In this time interval the solar wind speed was about 550 km/s and the Bz component of the interplanetary magnetic field was fluctuating with lowest value of about - 4nT. We believe that the high value of K index reported by Dourbes is due to either some local fluctuation or possibly an error of measurements. We expect quiet to unsettled conditions in the coming hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 087, gebaseerd op 14 stations.
