SOLAR ACTIVITY UPDATE: Solar Flare/Earth Bound Full Halo CME(Jan 19th,2012).

CME is heading for Earth, and they say strong geomagnetic storms are possible (although not guaranteed) when the cloud arrives this weekend. Analysis of Solar Active Regions and Activity from 18/2100Z to 19/2100Z: Solar activity was moderate. Region 1402 (N29E15) produced an M3/2n flare at 19/1605Z associated with a Type IV radio sweep and a full-halo CME (estimated plane-of-sky speed 1100 km/s). Region 1402 showed minor spot growth in its trailer portion and was classified as an Dko-type group with a beta magnetic configuration. Region 1401 (N18E13) showed some spot and penumbral development in its intermediate portion and was classified as an Eko-type with a beta-gamma magnetic configuration. Weak Type II radio sweeps were observed at 19/1252Z (estimated speed 933 km/s) and 19/1933Z (estimated speed 694 km/s). No new regions were numbered
