Bulletin

One C flare was released by the Sun in the past 24 hours: a C1.1 flare produced by beta region NOAA AR 2529, peaking at 02:02 UT on April 11. More C flares (probability 70%) are expected in the next 24 hours, with a slight chance (probability 10%) for an M flare, especially from AR 2529. A filament eruption centered near 10N25E was observed around 10:13 UT on April 10 and an associated CME was first observed by LASCO C2 at 11:48 UT. This CME may deliver a glancing blow on April 14. Solar wind speed varied between about 335 and 430 km/s in the past 24 hours, while the magnitude of the Interplanetary Magnetic Field ranged between 1 and 10 nT. Over the past 24 hours, geomagnetic conditions have been quiet to unsettled (K Dourbes between 1 and 3; NOAA Kp between 1 and 3). Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on April 11 and most of April 12. Late on April 12, and on April 13, the expected arrival of a high speed stream associated with a negative equatorial coronal hole may cause active (K Dourbes = 4) to moderate storm (K Dourbes = 6) conditions.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 040, gebaseerd op 22 stations.
