Bulletin

The first C-class flare (C3.8) of 2017 occurred on 12 January at 16:18 UT (peak), from new AR NOAA 2625 (that rotated into view yesterday). It was accompanied by a CME that will not affect Earth. This AR can produce more C-class flares.

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 ranged between K=2 and K=3. Solar wind speed is now at 360 km/s with interplanetary magnetic fields of 5 nT. The southern extension of the northern polar coronal hole may affect the Earth within 48 h, with K values up to 5.

Today's estimated international sunspot number (ISN): 026, based on 18 stations.
