Catania sunspot group 63 (NOAA AR 0977) is growing. It produced a B1.1 flare this morning. There is a slight possibility for a C-flare, although we expect solar activity to remain quiet. The Earth is currently located in a slow solar wind flow with rather average interplanetary magnetic field magnitude and fluctuating magnetic field direction. We do not expect any significant geomagnetic disturbance. TODAY'S ESTIMATED ISN : 009, BASED ON 02 STATIONS.
