Several C-class flares in past 24h. The strongest one was a C6.6 flare peaking at 03:04 UT. This region, and NOAA AR 1974, will likely produce more C-class and probably M-class flares. A new region rotating over the east limb is producing C-class flares also. A halo CME was first seen at 13:25 UT on February 16. This CME was a backsided event and not expected to arrive to the Earth. A C3.4 flare from NOAA AR 1977 that peaked at 14:00 UT on February 16 was related to a filament eruption, but no corresponding CME could be detected. Geomagnetic conditions have ranged from quiet to unsettled in past 24h. The possible arrival of a CME from February 13 and the fast solar wind from a coronal hole in the northern hemisphere may rise conditions to active levels.
