Bülletään

Solar activity was low with only modest B-flaring from Catania group 27 (NOAA 2506). The X-ray flux reachied an overall maximum of B5.1 level at 2:21UT. Catania group 27 showed some further consolidation and spreading of the magnetic footpoints. Solar flaring is mainly expected to remain below C level although Catania group 27 remains a prime candidate for an occasional C flare. Coronagraph data have confirmed that yesterdays CME had only limited angular extent and will not be geo-effective. No other Earth-directed CMEs have been observed. Solar wind was at near background conditions. Solar wind speed was mostly in the 350-400 km/s range. Total magnetic field reached a peak near 8.5 nT but was mostly in the 4-7 nT range. Bz was predominantly positive during the period, and the magnetic field phi angle was in the positive sector. Nominal solar wind conditions are expected to continue with enhanced conditions likely to set in from March 1 onwards due to a moderately high speed stream from the equatorial coronal hole connected to the northern polar coronal hole. Geomagnetic conditions were quiet (NOAA Kp 0-2) and are expected to continue to be quiet, while from March 1 onwards unsettled to active conditions are possible under the influence the coronal hole high speed stream.
