Bulletin

Beta-delta region NOAA AR 2320 released two low C flares during the past 24 hours. The strongest flare was a C1.1 flare which peaked at 21:31 UT on April 7. In the next 24 hours, more C flaring is expected, with a slight chance for an M flare, especially from AR 2320. Solar wind speed further decreased from about 400 to 350 km/s over the past 24 hours, while the Interplanetary Magnetic Field magnitude varied between 2 and 6 nT. Over the past 24 hours, geomagnetic conditions have been quiet (K Dourbes between 0 and 3; NOAA Kp between 1 and 2). There is a chance for active geomagnetic levels (K Dourbes = 4) on April 8 due to a possible glancing blow of the partial halo CME of April 4. Active to minor storm (K Dourbes = 5) intervals are possible in the second half of April 9, as a result of a glancing blow from the CME of April 6. Quiet to active geomagnetic activity is possible on April 10, as a new coronal hole high speed stream is expected to arrive near Earth.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 032, gebaseerd op 18 stations.
