Bulletin

Five C flares and two M flares were released by NOAA AR 2497 in the past 24 hours. The brightest flare was the M1.1 flare which peaked at 11:00 UT on February 15. It is not clear yet whether this flare was accompagnied by a CME, since no coronagraph data are available yet. More M flares (probability 60%) and C flares (probability 95%) are expected within the next 24 hours, especially from AR 2497. Solar wind speed varied between about 350 and 450 km/s in the past 24 hours, while the magnitude of the Interplanetary Magnetic Field ranged between 2 and 9 nT. Over the past 24 hours, geomagnetic conditions have been quiet to active (K Dourbes between 1 and 4; NOAA Kp between 1 and 3). Minor to moderate geomagnetic storm conditions (K Dourbes = 5-6) are possible on February 15, upon the expected arrival of the CME from February 11. The expected arrival of the high speed stream associated with a large southern coronal hole may cause active (K Dourbes = 4) to minor storm (K Dourbes = 5) levels on February 16 and 17.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 055, gebaseerd op 19 stations.
