Bulletin

There were no C flares during the past 24 hours. In the next 48 hours, eruptive conditions (C flaring) are possible, especially from NOAA AR 2139, 2140, and 2137. CACTUS detected a partial halo CME first observed by LASCO C2 at 5:48 UT on August 12. This CME is most probably associated with a backside eruption visible on STEREO A EUVI 195 images around 4:55 UT and hence will not be geo-effective. Over the past 24 hours, solar wind speed as observed by ACE varied between about 400 and 480 km/s, with current values around 440 km/s. The magnitude of the Interplanetary Magnetic Field (IMF) varied between 3 and 9 nT. Over the past 24 hours, geomagnetic conditions were quiet to active (K Dourbes between 2 and 4; NOAA Kp between 1 and 4). Quiet geomagnetic levels (K Dourbes < 4) are expected on August 13, 14 and 15.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 056, gebaseerd op 15 stations.
