Bulletin

The Sun released one M flare and ten C flares during the past 24 hours. The M1.6 flare (which peaked at 19:33 UT) and almost all C flares were produced by NOAA AR 2242. In the next 24 hours, C flaring is expected, with probability for an M flare around 40%. Over the last 24 hours, solar wind speed observed by ACE increased from about 430 to 480 km/s. The magnitude of the Interplanetary Magnetic Field (IMF) increased from about 6 to 10 nT. Over the past 24 hours, geomagnetic conditions were quiet (K Dourbes between 1 and 3; NOAA Kp between 2 and 3). Quiet to active geomagnetic levels (K Dourbes < 5) are expected on December 15, as well as on December 16 and 17 when we expect the arrival of a high speed stream associated with an equatorial coronal hole.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 116, gebaseerd op 06 stations.
