Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 104 Issued at 2200Z on 14 Apr 2019
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
with a slight chance for a C-class flare 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 403 km/s at 13/2139Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 4476 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).
