Bulletin

Flaring activity was low during the past 24 hours, and it is expected that the next 48 hours should be mostly quiet, with however a risk for C class flares from NOAA ARs 1670 and 1673. A CME was observed on Feb. 15, around 1736 UT on LASCO C2. It is a partial halo event, originating from a small eruptive event taking place to the south-east of NOAA AR 1671 around 1615UT. Due to the position of the source region, this event might arrive at Earth, although STEREO observations are scarce at the time this bulletin is prepared. Preliminary estimates give an arrival around Feb. 20, but this will be refined as new information is available. Unsettled to active conditions might be expected from this event. In the meanwhile, geomagnetic conditions are expected to be mostly quiet to unsettled for the next 48 hours.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 022, basierend auf 06 Stationen.
