Bulletin

A yet unnumbered, flux emerging region in the South-Eastern solar quadrant might develop flaring potential in the coming days. A large filament in the solar north-western hemisphere erupted Sunday evening around 21:45UT. The event was associated with a long duration C1.2 flare peaking at 23:39. The GOES proton flux level has crossed the event threshold (> 10 pfu for 10 MeV). LASCO observed a full-halo CME. In STEREO-B Cor2, the plane-of the sky speed is of the order of 600km/s. In the coming 3 days, we expect quiet geomagnetic conditions. The halo-CME of midnight Sept 29/30 is expected to arrive midnight October 2/3.

Today's estimated international sunspot number (ISN): 037, based on 17 stations.
