Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 14 Issued at 2200Z on 14 Jan 2025

IA.  Analysis of Solar Active Regions and Activity from 13/2100Z to
14/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C6 event observed at
14/1527Z from Region 3962 (N17E82). 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 on days one, two, and three (15 Jan, 16 Jan,
17 Jan).

IIA.  Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 527 km/s at 14/1716Z. Total IMF reached 9
nT at 14/1750Z. The maximum southward component of Bz reached -7 nT at
14/1724Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 402 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (15 Jan, 17
Jan) and quiet levels on day two (16 Jan).
