Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 309 Issued at 2200Z on 05 Nov 2023IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z 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
05/1143Z from Region 3480 (S09E40). There are currently 5 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (06 Nov, 07 Nov,
08 Nov).
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic
field has been at quiet to severe storm levels for the past 24 hours.
Solar wind speed reached a peak of 517 km/s at 05/1233Z. Total IMF
reached 44 nT at 05/1151Z. The maximum southward component of Bz reached
-26 nT at 05/0905Z. Electrons greater than 2 MeV at geosynchronous
orbit reached a peak level of 108 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at unsettled to major storm levels on day one (06 Nov), quiet to
active levels on day two (07 Nov) and unsettled to active levels on day
three (08 Nov).
