Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 65 Issued at 2200Z on 05 Mar 2024IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
05/1125Z from Region 3598 (S11W88). There are currently 10 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 day one (06 Mar) and expected to be low
with a slight chance for an M-class flare on days two and three (07 Mar,
08 Mar).
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 497 km/s at 04/2237Z. Total IMF reached 11
nT at 04/2100Z. The maximum southward component of Bz reached -6 nT at
04/2147Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 196 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on days one and two (06 Mar, 07 Mar) and quiet to
unsettled levels on day three (08 Mar).
