Bulletin

It was again AR1982-Cat46, now behind the solar west limb, that produced the strongest flaring activity in the past 24 hours. Several C-class flares were observed early Mar 2 but these correspond to only the flaring loop tops, the real magnitude of the event was presumably larger. The largest chance for major flaring in the coming days comes from AR1991-Cat59 which is undergoing significant magnetic restructuring. We estimate M-class flaring likely and a 25% chance for an X-class flare. Quiet geomagnetic conditions are expected.

Today's estimated international sunspot number (ISN): 112, based on 08 stations.
