Bulletin

Only C1 flares in past 24h, from NOAA AR 2010 (lost its delta configuration, now it is beta gamma) and 2015. The warning conditions for protons is maintained, as most of the big flare-producing ARs are now located in the western hemisphere. The shock from the CME of Mar 23 arrived at 19:25 UT on March 25. It caused active geomagnetic conditions at interplanetary (Kp = 4) and local (KDourbes = 4) indices. Quiet to unsettled geomagnetic conditions are expected for the next 48h.

Today's estimated international sunspot number (ISN): 076, based on 11 stations.
