Bulletin

There were five C flares on the Sun during the past 24 hours, released by NOAA AR 12003 and 12002. The brightest flare was a C5.0 flare produced by NOAA AR 12003 peaking at 09:40 UT on March 15. In the next 48 hours, the probability for C flares is high (90%) and for M flares around 35%, mainly from NOAA AR 12003 and 12002. In the past 24 hours, solar wind speed as observed by ACE decreased from about 450 km/s to about 400 km/s, while the magnitude of the Interplanetary Magnetic Field (IMF) dropped from about 8.5 to 4.5 nT. The effects of the coronal hole high speed stream have subsided. In the past 24 hours, quiet geomagnetic levels were registered (K Dourbes between 0 and 3; NOAA Kp between 1 and 2). Quiet geomagnetic conditions (K Dourbes < 4) are expected on March 15 and 16. Quiet to active conditions (K Dourbes < 5) are possible on March 17, due to a coronal hole high speed stream.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 078, basierend auf 11 Stationen.
