It was a sharp peak in the GOES-data. It is possible that it is originating from an active region now still behind the east limb. The back-ground X-ray radiation has increased a little, but we don't expect much flaring activity. The geomagnetic conditions became quiet again. TODAY'S ESTIMATED ISN : 000, BASED ON 09 STATIONS.
