Bulletin

Beta-gamma region NOAA AR 2454 produced seven C flares during the past 24 hours. The brightest flare peaked around 2:28 UT on November 23 at C8.7 level. C flares are expected within the next 24 hours, with a 30% chance for an M flare, especially from AR 2454. A CME associated with a filament eruption in the Southwest was first observed by LASCO C2 around 9:12 UT on November 22. Imagery from LASCO C2 and C3 and COR2A suggests that this CME is not Earthbound. The Earth is currently within a slow solar wind regime. Solar wind speed varied between 320 and 360 km/s in the past 24 hours, while the magnitude of the Interplanetary Magnetic Field first ranged between 1 and 5 nT. Over the past 24 hours, geomagnetic conditions have been quiet to unsettled (K Dourbes between 0 and 3; NOAA Kp between 0 and 1). Quiet to unsettled geomagnetic conditions (K Dourbes < 4) are expected on November 23 and 24. The expected arrival of a coronal hole high speed stream may cause active (K Dourbes = 4) geomagnetic levels on November 25, with a slight chance for a minor storm (K Dourbes = 5).

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 054, gebaseerd op 21 stations.
