Bulletin

A C2.0 flare with peak at 02:47 UT was observed from a recurrent active region (NOAA AR 2644) rotating into the visible disk, more C-class flares can be expected and M-class flares are possible (this region produced M-class flares in the previous rotation).

No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours.

Geomagnetic conditions have been at k = 1-2 levels. Solar wind speed is now at 315 km/s with interplanetary magnetic fields of 4 nT. A high speed solar wind from an equatorial coronal hole is expected within 48h. Active to minor storm conditions expected.

Today's estimated international sunspot number (ISN): 000, based on 23 stations.
