Bulletin
50% chance for C-class flaring is expected, mainly from NOAA AR 1682 and 1683. Active geomagnetic conditions are expected in the coming days due to the influence of small coronal hole. No geomagnetic effect is expected from the last 2 partial halo CME reported by CACTUS (CME lift off times 2013-02-26T09:36 and 2013-02-27T04:36, both Westward).
Today's estimated international sunspot number (ISN): 046, based on 07 stations.
