PLAIN
NOTE: the above forecasts are valid from 1230UT, 23 Dec 2017 until 25 Dec
2017
PREDICTIONS FOR 23 Dec 2017 10CM FLUX: 077 / AP: 008
PREDICTIONS FOR 24 Dec 2017 10CM FLUX: 077 / AP: 014
PREDICTIONS FOR 25 Dec 2017 10CM FLUX: 077 / AP: 007
COMMENT: 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.
TODAY'S ESTIMATED ISN : 027, BASED ON 08 STATIONS.
