Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 61 Issued at 2200Z on 02 Mar 2025IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z
Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C9 event observed at
01/2301Z. There are currently 9 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 (03 Mar, 04 Mar,
05 Mar).
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 652 km/s at 01/2125Z. Total IMF reached 6
nT at 02/2016Z. The maximum southward component of Bz reached -2 nT at
02/0541Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 1463 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on day one (03 Mar) and quiet to
minor storm levels on days two and three (04 Mar, 05 Mar).
