Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 256 Issued at 2200Z on 13 Sep 2018
IA. Analysis of Solar Active Regions and Activity from 12/2100Z to
13/2100Z: 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 (14 Sep, 15 Sep, 16 Sep).
IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 584 km/s at 13/1903Z. Total IMF reached 7
nT at 13/1012Z. The maximum southward component of Bz reached -6 nT at
13/1349Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 4910 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one, two, and three (14 Sep,
15 Sep, 16 Sep).
