Bulletin

There were no C flares during the past 24 hours. In the next 48 hours, eruptive conditions (C flaring) are possible, especially from AR 2139, 2137, and 2134. Over the past 24 hours, solar wind speed as observed by ACE increased from about 420 to a maximum of 560 km/s and then decreased again till the current values around 440 km/s. This is probably the effect of a coronal hole high speed stream. The magnitude of the Interplanetary Magnetic Field (IMF) varied between 4 and 9 nT. Over the past 24 hours, geomagnetic conditions were quiet (K Dourbes between 1 and 3; NOAA Kp between 1 and 3). Quiet geomagnetic levels (K Dourbes < 4) are expected on August 12, 13 and 14, with possible excursions to active levels on August 13 due to the expected arrival of a coronal hole high speed stream.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 052, gebaseerd op 15 stations.
