Bulletin

Solar X ray flux remained below B level and with no spotted regions on the visible disk chances for any flare occurrences remain very low. SoHO/LASCO C2 images show a very faint and slow CME first visible around 1:25 UT. It is primarily directed towards the south west and given its faint character its angular extent can not clearly be determined. Stereo A COR2 images however suggest that it can not be excluded that Earth is on its propagation path. Further analysis is ongoing but given its faint nature and slow speed any possible impacts should be fairly insignificant. Proton flux levels were at background values and are expected to remain so.

Solar wind was near nominal with speed between 360 and 400 km/s, total magnetic field below 7nT and Bz variable. The magnetic field phi angle was indicative of a positive sector connection. Solar wind may become slightly enhanced from March 8 onwards due to the extension of the northern polar coronal hole.

Geomagnetic conditions were quiet (local K Dourbes and NOAA Kp 1-2) and are expected to remain quiet, and later enhancing to unsettled by March 8.
