Bulletin
Solar activity has been very low, AR 2266 produced a C3.3 flare peaking at 20:48 UT on January 19. This AR has now a beta gamma magnetic configuration and may produce stronger flares. Geomagnetic conditions are quiet. The fast speed solar wind from a small equatorial coronal hole may still arrive in the coming hours, it is not expected to produce more than active conditions.
