An isolated C-flare is still possible. The small active region in the center of the northern hemisphere of the solar disk was numbered NOAA AR 1058. LASCO images show a CME yesterday at 03h54 on the east limb and one at 11h54 on the west limb of the sun. Based on STEREO images we expect their influence on earth to be minimal. We expect quiet solar conditions and quiet to unsettled geomagnetic conditions. TODAY'S ESTIMATED ISN : 019, BASED ON 02 STATIONS.
