Solar activity was very low with the X-ray flux remaining below C-level. NOAA AR 2505 was the only source of flaring activity with the largest a B5.1 flare peaking at 13:04UT. NOAA AR 2505 remains the most significant of the three regions located in the Western hemisphere and showed further flux emergence in the intermediate sections. It remains a potential source for flaring activity while X-ray levels may also remain below C-level. LASCO C2 images showed a halo CME first detected by CACTUS at 12:00 UT on February 21. From the absence of eruptions on the frontside of the Sun and the observation of a large eruption on the backside as seen by STEREO\EUVI at 195 Angstrom, it is clear that this halo CME is backsided and will not travel to Earth. Solar wind conditions showed a continued slow solar wind influence. Solar wind speed increased only slightly to around 360 km/s. Total magnetic field was in the 3.5-8nT range with Bz variable but never below -3.5nT. The magnetic field phi angle was also variable. Continued slow solar wind conditions are expected with later on February 24 a possible though probably weak influence of the extensions from the positive polarity Northern polar coronal hole. Geomagnetic conditions were quiet (both local K Dourbes and NOAA Kp 0-2). Quiet geomagnetic condition are expected with late on February 24 a possible weak increase due to the possible influence of the extensions from the positive polarity Northern polar coronal hole.
