Bulletin

Active conditions are expected to prevail for the next 48 hours, with risks of M class events from NOAA ARs 1861 and 1865. Both regions are magnetically complex enough for such class of flares, but somehow do not show anymore significant evolutions. Many C flares occurred in the past 24 hours related to these two regions. A noticeable one, a C6.2 event, occurred in AR 1865 on Oct. 11, 1228 UT peak time. It was associated with a CME, which is heading essentially eastward, compared to the Earth, and is therefore expected not to be geoeffective. We expect quiet geomagnetic conditions for the next 24-36 hours, and then unsettled to active conditions by the second half of Oct. 14, due a small coronal hole becoming geoeffective. Current interplanetary conditions are quiet.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 077, gebaseerd op 10 stations.
