Bulletin

There were four M flares and four C flares on the Sun during the past 24 hours, mostly released by NOAA AR 12002 and 11996. The brightest one was an M3.5 flare from NOAA AR 11996 peaking at 03:50 UT on March 11. In the next 48 hours, the probability for C flares is very high (95%) and for M flares around 75%, mainly from NOAA AR 12002 and 11996. There is a chance (35%) for an X flare. In the past 24 hours, solar wind speed as observed by ACE gradually decreased from around 340 km/s to around 300 km/s, while the magnitude of the Interplanetary Magnetic Field (IMF) varied between 3.5 and 6.5 nT. In the past 24 hours, geomagnetic conditions were quiet (K Dourbes between 0 and 3; NOAA Kp between 0 and 3). Quiet geomagnetic levels are expected on March 11, 12, and 13.

Today's estimated international sunspot number (ISN): 079, based on 12 stations.
