INFO FROM SIDC - RWC BELGIUM 2015 Feb 25 12:31:51

 

No C-class flares in past 24h. A partial halo CME was observed on February 24 at 10:24 UT (first seen by LASCO-C2). It originates from a partially backsided filament eruption around the southeast limb of the Sun. This CME is not expected to hit the Earth. Shortly after (around 11:00 UT) signs of an eruption are seen in NOAA AR 2289 (mostly dimmings), this may correspond to a slow CME (~300 km/s) directed towards the southwest, seen first at 14:24 UT by LASCO-C2. Additionally, a CME erupted at 23:36 UT (Feb 24) from a filament eruption close to NOAA AR 2291, again the speed was low (~200 km/s). These last two CMEs may have a minor influence on Earth by March 1st. Geomagnetic conditions have ranged from quiet to unsettled due to the vanishing effect of a fast speed stream, these conditions are expected to prevail in the next 48h.
