Report of Solar-Geophysical Activity 2022 Nov 12 2200 UTC
Prepared by the NOAA © SWPC and processed by SpaceWeatherLive.comJoint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 316 Issued at 2200Z on 12 Nov 2022
IA. Analysis of Solar Active Regions and Activity from 11-2100Z to 12-2100Z
Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M1 event observed at
12/0018Z from Region 3141 (N15W27). There are currently 3 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with
a chance for M-class flares and a slight chance for an X-class flare on
days one, two, and three (13 Nov, 14 Nov, 15 Nov).
IIA. Geophysical Activity Summary 11-2100Z to 12-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 500 km/s at 12/1810Z. Total IMF reached 14
nT at 11/2228Z. The maximum southward component of Bz reached -10 nT at
11/2126Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 137 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on days one, two, and three (13 Nov,
14 Nov, 15 Nov). Protons have a slight chance of crossing threshold on
days one, two, and three (13 Nov, 14 Nov, 15 Nov).
