Bülletään

Solar activity has been dominated by NOAA AR 1982 with several C-class flares and by recurrent AR NOAA 1967 slightly behind the east limb. This AR produced a long duration M1.0 flare with peak at 06:10 UT, related to a non-Earth directed CME. A second partial halo came from this AR at 16:00 UT on February 22, also not expected to affect the Earth. As this region rotates into view in next 24 - 48 h solar activity is expected to increase. A third partial halo CME was seen at 12:12 UT on February 22 by LASCO-C2, this one corresponded to a backside filament eruption in the south, not Earth directed. A weak transient arrived to ACE around 02:30 UT related most likely to the CMEs of February 20. Bz has been positive until now (with IMF magnitude close to 12 nT), with solar wind speeds close to 500 km/s, which led to only unsettled conditions so far. The situation may change in the next 24h if Bz turns negative. A small coronal hole could have also an effect on the geomagnetic conditions by February 24.
