Bulletin

Solar activity was low without any significant flare. NOAA active region 2436 remains the most complex region, but was inactive. The > 10 MeV proton flux was enhanced from 23:00 UT on, but remained well below the event threshold. This disturbance probably was due to the long duration flare of October 22. Flaring at the C-level is expected. No Earth-directed CMEs were observed in current available coronagraphic images.

The solar wind speed was at 400 km/s till 22UT, when the speed became variable between 400 and 500 km/s. The interplanetary magnetic field was at a constant magnitude around 5 nT. Quiet (K<3) to unsettled (K=3) geomagnetic conditions were observed, which are expected to continue for the next 24 hours. From the second half of October 24 the solar wind might be disturbed due to a glancing blow from the October 22 CME. This can result in (at maximum) minor storm (K=5) conditions.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 090, gebaseerd op 08 stations.
