Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 242 Issued at 2200Z on 29 Aug 2024

IA.  Analysis of Solar Active Regions and Activity from 28/2100Z to
29/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C7 event observed at
29/0418Z from Region 3806 (S10E56). There are currently 8 numbered
sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is likely to be moderate
with a slight chance for an X-class flare on days one, two, and three
(30 Aug, 31 Aug, 01 Sep).

IIA.  Geophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 360 km/s at 29/0853Z. Total IMF reached 18
nT at 28/2158Z. The maximum southward component of Bz reached -2 nT at
28/2357Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 131 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (30 Aug, 01
Sep) and quiet levels on day two (31 Aug). Protons have a slight chance
of crossing threshold on days one, two, and three (30 Aug, 31 Aug, 01
Sep).
