PLAIN
NOTE: the above forecasts are valid from 1230UT, 30 Nov 2017 until 02 Dec
2017
PREDICTIONS FOR 30 Nov 2017 10CM FLUX: 072 / AP: 012
PREDICTIONS FOR 01 Dec 2017 10CM FLUX: 071 / AP: 008
PREDICTIONS FOR 02 Dec 2017 10CM FLUX: 070 / AP: 005
COMMENT: Solar activity was at very low levels. Decaying sunspot region
NOAA 2689 was quiet and is approaching the NW limb. It has developed a
filament in its spotless trailing section. The 40 degrees long filament
is
rounding the SW limb quietly. 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 values around 400 km/s were recorded until about 19UT,
when the wind stream associated with the southern polar coronal hole (CH)
extension arrived and gradually drove the speed to values near 510 km/s
around 09UT. Bz oscillated between +7 nT and -9 nT. The interplanetary
magnetic field was mostly directed towards the Sun. Solar wind parameters
did not show any obvious sign of the 25 November CME which has most likely
missed the Earth.
The geomagnetic field was quiet to unsettled throughout the period, with
Kp
at active levels during the 03-06UT interval. Mostly quiet to unsettled
conditions are expected, with a possibility on another active episode.
TODAY'S ESTIMATED ISN : 011, BASED ON 09 STATIONS.
