Bulletin

An M1.7 flare was observed at 09:31 UT, it originated at an active region at the east limb that will rotate into view today. NOAA ARs 1640 and 1650 produced C-class flares. Activity at the C level is expected and probably more M-class events. Geomagnetic conditions are quiet. The effect of a small coronal hole is expected to be seen at the Earth between 24 and 48 hours, increasing geomagnetic conditions (probably up to active levels).

Today's estimated international sunspot number (ISN): 101, based on 04 stations.
