Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 108 Issued at 2200Z on 17 Apr 2016
IA. Analysis of Solar Active Regions and Activity from 16/2100Z to
17/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 2 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be low with
a slight chance for an M-class flare on days one, two, and three (18
Apr, 19 Apr, 20 Apr).
IIA. Geophysical Activity Summary 16/2100Z to 17/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 478 km/s at 16/2349Z. Total IMF reached 13
nT at 17/1937Z. The maximum southward component of Bz reached -5 nT at
17/0412Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 1036 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on days one and two (18 Apr, 19 Apr) and
quiet levels on day three (20 Apr).
