Four C-class flares were detected during last 24 hours. The C-class flares are possible, in particular from the Catania sunspot group 79 (NOAA AR 1667). The strongest observed flare was C8.7 flare peaking at 00:21 UT, on February 6. The long duration flare originated from the Catania sunspot group 79 (NOAA AR 1667) and was associated with the type II radio burst and the CME. Due to the data gap it is not possible to determine when the CME first time appeared in the SOHO/LASCO C2 field of view. The C1.3 flare peaking at 03:16 UT on February 6, was associated with the partial halo CME. From the currently available data it seems that the CME was directed somewhat northward of the Sun-Earth line. Therefore, only arrival of a CME-driven shock at the Earth is expected. The additional information will be possible once the data are available. The interplanetary magnetic field magnitude is about 4 nT. The solar wind speed is still low, having value of about 320 km/s. The fast flow from the small low-latitude coronal hole in the southern hemisphere might arrive on February 9. The fast flow associated with the low-latitude coronal hole in the northern hemisphere should arrive today. We expect quiet to possibly active geomagnetic conditions in the next 48 hours.
