Bulletin

The flaring activity is at the low C-class level. The last C-class flare reported was C3.2 flare which peaked at 16:04 UT, on January 14. The flare originated from the Catania sunspot group 98 (NOAA AR 1944). The background X-ray flux has high B-level, so we expect C-class flares, while M-class flares are not probable. The Catania sunspot group 98 (NOAA AR 1944) just rotated behind the West solar limb and we maintain the warning condition for a proton event for the following 24 hours. The eruption, originating from the Catania sunspot group 9 (NOAA AR 1950) at about 08:30 UT on January 14, was accompanied by coronal dimming, EIT wave and a post- eruption arcade observed by SDO/AIA. Due to data gap the associated partial halo CME was first seen in the SOHO/LASCO C2 field of view only at the height of about 4.5 solar radii, at 11:36 UT on January 14. The CME had a width of about 180 degrees and approximate speed of 400 km/s. The bulk of the CME mass was directed somewhat northward of the Sun-Earth line and we expect at least the glancing blow from the associated CME-driven shock wave, on January 18. The solar wind speed is still slowly decreasing and its current value is about 500 km/s. The interplanetary magnetic field is stable with the magnitude between 2 and 3 nT. The geomagnetic conditions are currently quiet and expected to remain so in the following 24 hours.
