Bulletin

The only C-class flare reported during last 24 hours was the long duration C2.4 flare peaking at 06:40 UT. The flare was associated with eruption of a filament channel between the Catania sunspot groups 79 (NOAA AR 1667), and 80 (NOAA AR 1670), coronal dimming and post-eruption arcade. Occasional C-class flares are possible but not very probable. The associated CME was directed northward and appeared first time in the SOHO/LASCO C2 field of view at 06:48 UT. From the currently available data it seems that the width of the CME was about 100 degrees. Due to the position of the CME source region close to the central meridian, it is possible that this CME will arrive at the Earth. More exact prediction will be available with the arrival of the new data. The solar wind speed has reached maximum value of about 480 km/s late on February 8. The speed of the solar wind is decreasing and is now around 400 km/s. The interplanetary magnetic field magnitude is about 5 nT. The halo CME from February 6 (associated with the C8.7 flare) might still arrive today. The arrival of a CME-driven shock wave associated with the partial-halo CME on February 6 (related with the C1.3 flare) can be expected on early February 10. We expect quiet to possibly unsettled geomagnetic conditions.
