Bülletään

Solar activity was low, no C-class flares in past 24 h. There is only one region visible on disk (Catania group 67, NOAA active region 2692) with beta magnetic field configuration. C-class flaring is possible.

Proton flux levels are at background values and are expected to remain so. No Earth-directed seems were observed.

Solar wind speed is at 380 km/s with interplanetary magnetic field magnitude of 7 nT. A sector boundary crossing was seen around 22:00 UT on 22 December, with polarity changing from positive to negative. The arrival of a high speed stream from a negative coronal hole is expected within 24 h. Geomagnetic conditions have been quiet, active periods and possibly minor storms are possible under the influence of the high speed stream.
