Bulletin
We expect quiet conditions to prevail for the solar activity, with a small risk of an isolated C flare from NOAA AR 1670. Geomagnetic conditions are expected to be quiet to unsettled any time now as the southern flank of the CME of Feb. 9 arrives at Earth later today. Geomagnetic conditions should be back to quiet levels by the second half of Feb. 13.
