Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 244 Issued at 2200Z on 01 Sep 2017
IA. Analysis of Solar Active Regions and Activity from 31/2100Z to
01/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
01/1537Z from Region 2674 (N13E38). There are currently 4 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be low with a
slight chance for an M-class flare on days one, two, and three (02 Sep,
03 Sep, 04 Sep).
IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 764 km/s at 01/1349Z. Total IMF reached 10
nT at 01/0550Z. The maximum southward component of Bz reached -8 nT at
01/0839Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 1768 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on days one and two (02 Sep, 03 Sep) and
quiet to unsettled levels on day three (04 Sep).
