Bulletin

No major flares in past 24h, the largest one was a C1.6 from NOAA AR 1748 peaking at 12:37 UT on May 15. This AR is still expected to produce major flares. NOAA AR 1745 has potential for M-class flares. The proton flux remains over the threshold of 1 protons/cm2-s-sr for the past 24h. This increase is related to the CME and X1.2 solar flare from May 15. Geomagnetic conditions have ranged from unsettled to active. ACE data shows an ICME arriving at 08:00 UT on May 15, most likely corresponding to the CME of May 12. A glancing blow of the CME from May 15 can be expected in the first half of May 17, increasing geomagnetic conditions up to storm levels (estimated max K = 6).

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 139, gebaseerd op 08 stations.
