Bulletin

Solar activity is dominated by NOAA ARs 1652 and 1654, which both have the potential for M class flares in the coming 48 hours, with a small risk of an X class flare from AR 1654. Two M flares occurred on Jan. 13: a M1.0 flare, peaking at 00:50 UT, and a M1.7 flare, peaking at 08:38 UT, both in AR 1652. The second one was associated with a metric type II burst. Both flares were quite impulsive with no obvious CME signatures (but no LASCO observations are yet available for the second event). If this is confirmed, geomagnetic conditions should be mostly quiet during the next 48 hours, but due to the risk of a geoeffective CME, warning conditions are issued.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 084, gebaseerd op 07 stations.
