Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 109 Issued at 2200Z on 19 Apr 2018
IA. Analysis of Solar Active Regions and Activity from 18/2100Z to
19/2100Z: Solar activity has been at very low levels for the past 24
hours. There is currently 1 numbered sunspot region 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 (20
Apr, 21 Apr, 22 Apr).
IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 302 km/s at 19/0231Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 1782 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on days one and two (20 Apr, 21 Apr) and
quiet to unsettled levels on day three (22 Apr).
