Report of Solar-Geophysical Activity 2020 Nov 09 2200 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 314 Issued at 2200Z on 09 Nov 2020IA. Analysis of Solar Active Regions and Activity from 08-2100Z to 09-2100Z Solar activity has been at very low levels for the past 24
hours. There are currently 1 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is likely to be low with a
slight chance for an M-class flare on days one and two (10 Nov, 11 Nov)
and expected to be very low with a chance for a C-class flares and a
slight chance for an M-class flare on day three (12 Nov).
IIA. Geophysical Activity Summary 08-2100Z to 09-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 454 km/s at 09/0025Z. Total IMF reached 5 nT at
09/2052Z. The maximum southward component of Bz reached -2 nT at
09/1358Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 820 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on days one, two, and three (10 Nov, 11 Nov, 12
Nov).
