PLAIN
NOTE: the above forecasts are valid from 1230UT, 07 Dec 2017 until 09 Dec
2017
PREDICTIONS FOR 07 Dec 2017 10CM FLUX: 070 / AP: 008
PREDICTIONS FOR 08 Dec 2017 10CM FLUX: 072 / AP: 007
PREDICTIONS FOR 09 Dec 2017 10CM FLUX: 072 / AP: 007
COMMENT: The solar activity remained quiet over the past 24 hours. No
C-class flare and above have been recorded. The bipolar sunspot (Catania
sunspot group 65, NOAA Active Region 2690) has produced one small B-class
flare. Quiet flaring conditions are expected for the next 24-hour period.
No Earth directed Coronal Mass Ejection has been observed. The greater
than
10 MeV solar protons flux remained at nominal levels over the past 24 hours
and is expected to remain so.
The Earth remained under the influence of the solar wind stream associated
with the Coronal Hole (which has crossed the central meridian on Dec 01).
The wind speed has gradually decreased from 550 km/s to 500 km/s. The
interplanetary magnetic field magnitude remained below 6 nT, and the Bz
component fluctuated between -5 and 5 nT. The solar wind conditions are
expected to continue to decline and return to nominal conditions.
Geomagnetic conditions were quiet to unsettle (local K Dourbes 1-3, NOAA
Kp
2-3) due to the solar wind stream associated with the Coronal Hole. The
conditions are expected to return to the nominal level as the solar wind
is
declining.
TODAY'S ESTIMATED ISN : 010, BASED ON 10 STATIONS.
