Joint USAF/NOAA Report of Solar and Geophysical Activity

SDF Number 324 Issued at 2200Z on 19 Nov 2024

IA. Analysis of Solar Active Regions and Activity from 18-2100Z to 19-2100Z

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 19/0000Z from Region 3889 (S09W95). There are currently 8 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 (20 Nov, 21 Nov, 22 Nov).
IIA. Geophysical Activity Summary 18-2100Z to 19-2100Z
The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 433 km/s at 19/1617Z. Total IMF reached 10 nT at 19/1706Z. The maximum southward component of Bz reached -8 nT at 19/1044Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 745 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet levels on days one, two, and three (20 Nov, 21 Nov, 22 Nov).
