Bulletin

Solar activity was dominated by NOAA AR 2257 which is rotating over the west limb at present. It produced several C-class flares with the strongest being a C9.7 with peak at 03:47 UT. This region still has potential for M-class flares. Geomagnetic conditions are quiet, the solar wind speed is around 400 km/s with magnetic field intensities of 6 nT. Active conditions with isolated minor storm levels can be reached if the CME from Jan 12 arrives to the Earth.

Today's estimated international sunspot number (ISN): 059, based on 09 stations.
