Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 332 Issued at 2200Z on 28 Nov 2017
IA. Analysis of Solar Active Regions and Activity from 27/2100Z to
28/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 1 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
with a slight chance for a C-class flare on days one, two, and three (29
Nov, 30 Nov, 01 Dec).
IIA. Geophysical Activity Summary 27/2100Z to 28/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 490 km/s at 28/0117Z. Total IMF reached 11
nT at 28/0057Z. The maximum southward component of Bz reached -8 nT at
28/0031Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 212 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to minor storm levels on day one (29 Nov), quiet to
active levels on day two (30 Nov) and quiet to unsettled levels on day
three (01 Dec).
