Report of Solar-Geophysical Activity 2022 Nov 03 2200 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 307 Issued at 2200Z on 03 Nov 2022IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z
Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
03/0723Z from Region 3136 (S08E09). There are currently 5 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, two, and three (04 Nov,
05 Nov, 06 Nov).
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 590 km/s at 03/2023Z. Total IMF
reached 10 nT at 03/0937Z. The maximum southward component of Bz reached
-10 nT at 03/1507Z. Electrons greater than 2 MeV at geosynchronous
orbit reached a peak level of 2584 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at unsettled to minor storm levels on days one and two (04 Nov, 05
Nov) and quiet to active levels on day three (06 Nov).
