Bulletin
NOAA AR 1913 on the west limb was responsible for most of the flaring activity yesterday. NOAA AR 1908, 1909 and 1912 are likely to cause C-flares. The chance for C-flares is around 50%, the chance for M-flares around 15%. X-flares are unlikely. The solar wind speed is around 400 km/s. A magnetic structure in the slow solar wind carries a negative magnetic z-component resulting in unsettled geomagnetic conditions. A coronal hole located just above the solar equator approached the central meridian. This coronal hole might influence the earth magnetosphere in a few days.
