Bulletin

NOAA 2222 produced 3 C-class flares over the last 24 hours, NOAA 2221 and 2219 each 2. The latter group was also the source of the strongest event, a C6.5 flare peaking at 13:49UT. These three groups have all some mixed magnetic polarities. The other groups were quiet. C-class flaring is expected, with a small chance on low-level M-class flares. CACTus reported two wide angle CMEs. The first wide CME (94 degrees) became visible in LASCO/C2 on 28 November at 22:00UT, and may be related to the filament eruption earlier that day. The other wide CME (110 degrees) was first observed on 29 November at 00:12UT. However, this seems to be a superposition of at least 2 separate CMEs, with the part first visible at 02:24UT related to a prominence eruption around 02:00UT at the northeast limb. None of the observed CMEs has an Earth-directed component. Solar wind speed was stable between 360 and 430 km/s. The IMF is directed towards the Sun, with Bz mostly positive varying between 0 and +10 nT, and an occasional negative excursion to -7 nT. The geomagnetic field was quiet (K<3). Geomagnetic conditions are expected to be quiet to unsettled.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 101, gebaseerd op 05 stations.
