Several C-flares and two M-flares were observed during the past 24 hours, many occurring short after each other. Catania sunspot region 87 (NOAA AR 1928) is most active. The probability for C-flares remains high, around 80%, and for M-flares around 40%. An X-flare is possible but unlikely.
Solar wind speed remains around 350 km/s and the magnitude of the interplanetary magnetic field is still around 5 nT, as observed by ACE. Current geomagnetic conditions are quiet (Kp<4) and are expected to remain so during the next 48 hours. Towards the end of day 3, geomagnetic conditions might become unsettled to active, due to the effects of a coronal hole, which is currently at the central meridian and a latitude of 25 to 50 degrees.
