Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 243 Issued at 2200Z on 30 Aug 2024

IA.  Analysis of Solar Active Regions and Activity from 29/2100Z to
30/2100Z: Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M3 event observed at
30/1220Z from Region 3806 (S11E40). There are currently 9 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
(31 Aug, 01 Sep, 02 Sep).

IIA.  Geophysical Activity Summary 29/2100Z to 30/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 431 km/s at 30/0715Z. Total IMF reached 20
nT at 30/0603Z. The maximum southward component of Bz reached -14 nT at
30/0811Z.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (31 Aug, 01 Sep)
and quiet levels on day three (02 Sep). Protons have a slight chance of
crossing threshold on days one, two, and three (31 Aug, 01 Sep, 02 Sep).
