NOTE: the above forecasts are valid from 1230UT, 22 Nov 2017 until 24 Nov
2017
PREDICTIONS FOR 22 Nov 2017 10CM FLUX: 074 / AP: 012
PREDICTIONS FOR 23 Nov 2017 10CM FLUX: 074 / AP: 005
PREDICTIONS FOR 24 Nov 2017 10CM FLUX: 074 / AP: 004
COMMENT: Over the past 24 hours solar activity has been quiet. No
significant flares have been recorded. All Active Regions (AR) have shown
low levels of activity. No Earth directed Coronal Mass Ejections (CMEs)
have been detected. A small back-sided CME was detected off of the West
solar limb, but is not expected to reach the Earth. The greater than 10MeV
proton flux remained at background levels over the past 24 hours. Solar
activity is expected to remain low over the next 24 hours with a low
probability of C-class flares.
The solar wind speed been decreasing from 650 to 500 km/s over the past
24
hours. The total magnetic field strength has fluctuated around 5 nT. The
Bz
component has fluctuated between positive and negative, between -5 and
+5
nT. Geomagnetic conditions ranged between Kp index 2-5 (NOAA) and local
K
index 1-4 (Dourbes) over the past 24 hours. A positive polar coronal hole
was positioned in the Western hemisphere of the Sun and produced a high-
speed stream (HSS) that enhanced solar wind speeds and as a consequence
increased geo-activity levels. Geomagnetic conditions are expected to
return to quiet conditions throughout the day.
TODAY'S ESTIMATED ISN : 000, BASED ON 19 STATIONS.
