Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 337 Issued at 2231Z on 03 Dec 2024IA. 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 C5 event observed at
03/0300Z. There are currently 7 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 (04 Dec, 05 Dec,
06 Dec).
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 460 km/s at 03/1851Z. Total IMF reached 14
nT at 03/0047Z. The maximum southward component of Bz reached -8 nT at
03/1711Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 103 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on days one, two, and three (04 Dec, 05 Dec, 06
Dec).
