Bulletin

The Sun produced two C flares in the past 24 hours. The brightest flare was a C3.1 flare released by NOAA AR 2468, peaking at 2:04 UT on December 19. C flares are possible within the next 24 hours, with a chance (15%) for an M flare. During the past 24 hours, the solar wind speed gradually decreased from about 400 to 350 km/s with intermittent peaks up to 440 km/s. The magnitude of the Interplanetary Magnetic Field varied between 1 and 6 nT. During the past 24 hours, quiet to unsettled geomagnetic levels were registered (K Dourbes between 1 and 3, NOAA Kp between 1 and 3). Due to the expected arrival of the December 16 CMEs, active to minor storm conditions (K Dourbes = 4-5) are expected on December 19, with a chance for moderate to major storm conditions (K Dourbes = 6-7). Quiet to unsettled geomagnetic levels are expected on December 20 and 21, with a chance for active (K Dourbes = 4) excursions.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 049, gebaseerd op 11 stations.
