Bulletin

Solar activity is expected to be very low for the next 48 hours, with a low probability of an isolated C flare from NOAA AR 1670. Geomagnetic activity is expected to be mostly quiet for the next 48 hours. On Feb.13, unsettled to active conditions were observed locally (Dourbes, K=4) from 18 to 21 UT and at planetary level (Kp=4) from 21 to 24 UT. This corresponds to a short period of Bz excursions close to -10 nT in the same time period. The source of such (modest) activity is unclear at the moment.

Today's estimated international sunspot number (ISN): 021, based on 08 stations.
