Bulletin

The X-ray radiation is at the top B-level reaching the low C-level with small and narrow peaks. The chance for more C-flares is between 60 and 80%. NOAA AR 2002 (S18W49) and 2006 (at the west limb, northern hemisphere) have the highest probability for C and M-flares. An isolated M-flare is possible. A recurrent northern coronal hole (CH) passed the central meridian on March 13. The CH is present since December 2013. The influence was limited during its passage in December 2013 and January 2014. In February, it's influence was masked due several CME arrivals. We expect only a minor influence with a Kp not exceeding 3. The solar wind parameters are at the moment such that there are no near Earth environment geomagnetic disturbances.

Today's estimated international sunspot number (ISN): 091, based on 14 stations.
