Bulletin

There were five C flares and one M flare on the Sun during the past 24 hours, released by NOAA AR 12002 and 11996. The M2.6 flare was produced by NOAA AR 11996 and peaked at 11:05 UT on March 12. In the next 48 hours, the probability for C flares is very high (above 90%) and for M flares around 60%, mainly from NOAA AR 12002 and 11996. There is a slight chance (25%) for an X flare. In the past 24 hours, solar wind speed as observed by ACE varied between about 270 and 330 km/s, while the magnitude of the Interplanetary Magnetic Field (IMF) varied between 4 and 6. In the past 24 hours, geomagnetic conditions were quiet (K Dourbes between 0 and 2; NOAA Kp between 1 and 2). Quiet geomagnetic levels are expected on March 12, 13, and 14.

Today's estimated international sunspot number (ISN): 092, based on 15 stations.
