Bulletin

There is ongoing C-flaring activity at the moment. We expect this trend to be continued. NOAA AR 2014 has to highest probability to cause C-flares. The chance for M-flares is less than 50%. The planetary K index is 3 indicating unsettled conditions. This is due to the negative value of the z-component of the interplanetary magnetic field. There is a coronal hole at the equator which might become geoeffective. The impact is expected to be limited however.

Today's estimated international sunspot number (ISN): 088, based on 10 stations.
