Bulletin

NOAA AR 2010 released this morning a C3.4 flare and is still candidate for more C-flaring activity. The global probability for C-flares is well above 50%. The solar wind speed is below 400 km/s, this is a slow solar wind. A small increase in the magnetic field strength followed by a smooth increase in the solar wind speed this morning can possibly be linked with the northern coronal hole which passed the central meridian on March 13. The geomagnetic impact is negligible.

Today's estimated international sunspot number (ISN): 096, based on 10 stations.
