Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 248 Issued at 2200Z on 05 Sep 2018
IA. Analysis of Solar Active Regions and Activity from 04/2100Z to
05/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 0 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (06 Sep, 07 Sep, 08 Sep).
IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 513 km/s at 05/1304Z. Total IMF reached 7
nT at 05/0108Z. The maximum southward component of Bz reached -6 nT at
05/0108Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 2506 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (06 Sep, 08
Sep) and quiet to active levels on day two (07 Sep).
