Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 247 Issued at 2200Z on 04 Sep 2017
IA. Analysis of Solar Active Regions and Activity from 03/2100Z to
04/2100Z: Solar activity has been at high levels for the past 24 hours.
The largest solar event of the period was a M5 event observed at
04/2033Z. There are currently 5 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be moderate
with a chance for X-class flares on days one, two, and three (05 Sep, 06
Sep, 07 Sep).
IIA. Geophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 524 km/s at 04/2007Z. Total IMF reached 9
nT at 04/2019Z. The maximum southward component of Bz reached -6 nT at
04/1649Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 15826 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (05 Sep) and quiet levels
on days two and three (06 Sep, 07 Sep). Protons have a slight chance of
crossing threshold on days one, two, and three (05 Sep, 06 Sep, 07 Sep).
