Bulletin

The two active regions (ARs) visible on the disk NOAA AR 2778 and 2779 have decayed in complexity and size. Four C-class flares were observed from AR 2779, the largest was a C4.3 peaking at 11:50 UT on 29 October (partially reported yesterday). More C-class flares can be expected, and M-class flares remain possible but less likely.

No Earth directed CME was observed in the past 24 hours.

The greater than 10 MeV proton flux was at background levels over the past 24 hours. It is expected to stay at background levels for the next 24 hours. The greater than 2 MeV electrons are above the 10^3 pfu threshold. The electrons are expected to descend below the threshold in the next 24 hours.

The speed of the solar wind decreased from 465 to 435 km/s in the past 24 hours. Bz was never below -5 nT and B reached 6 nT. The solar wind speed is expected to remain at low speeds over the next 24 hours.

The geomagnetic conditions reached active levels both locally and globally (KDourbes = 4, Kp = 4). Mostly quiet to unsettled conditions can be expected in the next 24 hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 031, gebaseerd op 10 stations.
