After about two weeks without C-class flares, two C-class flares were reported this morning. The strongest one was C2.8 flare (peaked at 02:39 UT) which originated from the Catania sunspot group 7 (NOAA AR 2480). We expect isolated C-class flares in the coming hours (probability is > 50%). The large filament situated at the southern solar hemisphere erupted at about 22:15 UT on January 14. The filament eruption was associated with coronal dimming and partial halo CME. The CME was first seen in the SOHO LASCO C2 field of view at about 23:36 UT, had angular width of about 280 degrees and speed of about 250 km/s. This CME might arrive at the Earth late on January 18 or in the morning of January 19. The Earth is inside the slow solar wind speed (400 km/s) and the interplanetary magnetic field magnitude is about 4 nT. Geomagnetic conditions are quiet and we expect them to remain so in the coming hours.
Today's estimated international sunspot number (ISN): 041, based on 13 stations.
