Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 90 Issued at 2200Z on 31 Mar 2018
IA. Analysis of Solar Active Regions and Activity from 30/2100Z to
31/2100Z: 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 (01
Apr, 02 Apr, 03 Apr).
IIA. Geophysical Activity Summary 30/2100Z to 31/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 469 km/s at 31/0016Z. Total IMF reached 7
nT at 31/0105Z. The maximum southward component of Bz reached -5 nT at
31/0001Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 9268 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (01 Apr, 02 Apr, 03
Apr).
