Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 104 Issued at 2200Z on 14 Apr 2018

IA.  Analysis of Solar Active Regions and Activity from 13/2100Z to
14/2100Z: 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
on days one, two, and three (15 Apr, 16 Apr, 17 Apr).

IIA.  Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 467 km/s at 13/2125Z. Total IMF reached 5 nT at
14/1340Z. The maximum southward component of Bz reached -4 nT at
14/1909Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 20707 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (15 Apr, 16 Apr, 17
Apr).
