Bulletin

Solar activity has been at active levels over the last 24 hours. 6 C- and 4 M-class flares were recorded, the strongest reached M4-level and peaked at 22:10UT in NOAA 1967. This region has nearly rounded the southeast limb and was responsible for all 10 flares. These occurred near areas of mixed magnetic polarities to the northeast and south of the big main spot, which is still very close to the limb. NOAA 1968 near the northeast limb is a lot smaller and did not produce flares. The x-ray background flux has been all day above the C1-level. Active conditions are expected to continue, with a slight chance on an X-class flare. The CMEs associated with NOAA 1967's flaring activity were directed to the east and away from Earth. Solar wind speed has been declining to values currently just above 300 km/s, with Bz varying between -5 and +5 nT. Geomagnetic conditions have been quiet and are expected to remain so.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 056, gebaseerd op 10 stations.
