Bulletin

Four C flares were released by NOAA AR 2529 in the past 24 hours. The brightest one was a C1.8 flare which peaked at 07:51 UT on April 12. More C flares (probability 75%) are expected in the next 24 hours, with a slight chance (probability 10%) for an M flare, especially from AR 2529. CACTUS detected a partial halo CME at 03:24 on April 12. Close inspection of EUVI A imagery revealed that this CME was associated to a backside event, and will not be geoeffective. Solar wind speed varied between about 340 and 470 km/s in the past 24 hours, while the magnitude of the Interplanetary Magnetic Field ranged between 1 and 12 nT. Over the past 24 hours, geomagnetic conditions have been quiet to unsettled (K Dourbes between 1 and 3; NOAA Kp between 1 and 3). Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on most of April 12. Late on April 12, and on April 13 and 14, the expected arrival of a high speed stream associated with a negative equatorial coronal hole may cause active (K Dourbes = 4) to moderate storm (K Dourbes = 6) conditions.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 038, basierend auf 26 Stationen.
