Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 116 Issued at 2200Z on 25 Apr 2020
IA. Analysis of Solar Active Regions and Activity from 24/2100Z to
25/2100Z: 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
on days one, two, and three (26 Apr, 27 Apr, 28 Apr).
IIA. Geophysical Activity Summary 24/2100Z to 25/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 465 km/s at 25/0526Z. Total IMF reached 7
nT at 25/0020Z. The maximum southward component of Bz reached -5 nT at
25/0034Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 211 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one, two, and three (26 Apr,
27 Apr, 28 Apr).
III. Event probabilities 26 Apr-28 Apr
