Bulletin

There is ongoing C-flare activity. The source region is NOAA 2010 (S15E48 on March 19). We expect further C-flaring activity with a chance of M-flares of 30%. At the time of the C4.7 flare (March 18, peak 22:52UT) and the C1.8 (March 19, peak 03:44UT) a type II radio outburst was detected, which typically indicates that a coronal mass ejection is associated with the flare. Because of the position of the source region, the CME's are not expected to have an impact on the Earth. The solar wind has a speed below 400 km/s. The magnetic field vector changed pointing direction yesterday, March 18. A vague footprint of a coronal hole is visible in ACE data. Nevertheless, the geomagnetic conditions are quiet and are expected to stay quiet.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 097, gebaseerd op 18 stations.
