The largest one was an M2.3 flare with peak at 13:41 UT on January 19. They are all coming from NOAA AR 11041 (old 11039, Catania 37). More M flares are likely. Geomagnetic activity is quiet but can turn to unsettled levels. Isolated active levels are possible, due to the arrival of the fast solar wind from a coronal hole.
