Bülletään

Solar activity was at very low levels. Decaying sunspot region NOAA 2689 was quiet. The leading part of the prominent 40 degrees long filament has started to round the SW limb. No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal levels.

Quiet flaring conditions are expected, with a slight chance on an isolated C-class flare.

Solar wind speed undulated between 400 and 430 km/s, with Bz oscillating between -6 nT and +7 nT. The interplanetary magnetic field was mostly directed towards the Sun.

The geomagnetic field was quiet throughout the period. Mostly quiet to unsettled conditions are expected, with a possibility on an active episode if the glancing blow from the 25 November CME arrives or the wind stream of the negative polar coronal hole (CH) extension intensifies.
