Bulletin
Solar activity has been very low, the ARs visible on disk have produce no C-class flares. Only a C1.0 flare occurred at 05:52 UT, it originated in an AR behind the east limb, rotating now into view. This AR may increase solar activity. Geomagnetic conditions have been quiet and are expected to remain so. The fast speed solar wind from a small equatorial coronal hole may arrive today, it is not expected to produce more than active conditions.
