Bulletin

The strongest flare, out of four C-class flares reported during last 24 hours, was C6.7 flare (peaked at 19:14 UT) on December 08. The flare originated from the NOAA AR 2463 and was associated with the EIT wave and the coronal dimming indicating the presence of the associated, possibly Earth directed CME. Due to the current unavailability of coronagraph data it is not possible to estimate CME width or speed, more will be reported as soon as coronagraph data become available. We expect C-class flares in the coming hours.

The solar wind speed has decreased to about 450 km/s, and the interplanetary magnetic field is stable with the magnitude of 5 nT. The geomagnetic conditions are quiet at the moment. We expect quite to active geomagnetic conditions this evening and tomorrow morning due to awaited arrival of the fast flow associated with the equatorial coronal hole (seemingly connected with the northern polar coronal hole) which has reached the central meridian late on December 06.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 072, gebaseerd op 17 stations.
