Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 111 Issued at 2200Z on 21 Apr 2018
IA. Analysis of Solar Active Regions and Activity from 20/2100Z to
21/2100Z: 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 very low
with a chance for a C-class flares on days one, two, and three (22 Apr,
23 Apr, 24 Apr).
IIA. Geophysical Activity Summary 20/2100Z to 21/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 630 km/s at 20/2357Z. Total IMF reached 6
nT at 21/0701Z. The maximum southward component of Bz reached -5 nT at
20/2308Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 21310 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (22 Apr) and quiet levels
on days two and three (23 Apr, 24 Apr).
