Bulletin

Solar activity is expected to be mostly quiet with a risk of an isolated C flare from NOAA AR 1670. Two eruptive events occurred relatively close to the west limb, late on Feb. 12. One is a filament eruption taking place in the southern hemisphere. Owing to the current coronagraphic observations, they do not appear to be geoeffective. Geomagnetic activity is expected to be low for the next 48 hours.

Today's estimated international sunspot number (ISN): 025, based on 08 stations.
