Bulletin

Solar activity was dominated by C-class flares from NOAA AR 2290 and 2994. The strongest was a C3.7 flare from NOAA AR 2290 peaking at 05:13 UT. More C-class flares are expected with chances of M-class flaring. Two full halo CMEs occurred on February 28. Both were backsided events. One starting at 04:36 UT (LASCO-C2) and the other at 21:36 UT. Additionally a CME directed to the NW was seen erupting at 15:12 UT, this is a frontside event coming from north of NOAA AR 2292. This CME was slow, it may arrive to the Earth on March 4 and cause at most minor storm conditions. Geomagnetic activity was dominated by a fast speed stream that caused active conditions with isolated minor storm periods starting at midnight on March 1 and still ongoing. The solar wind speed is around 500 km/s with magnetic fields intensities of 10 nT. More active conditions can be expected for today.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 054, gebaseerd op 14 stations.
