SDF Number 117 Issued at 2200Z on 26 Apr 2020
IA. Analysis of Solar Active Regions and Activity from 25/2100Z to
26/2100Z: 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 (27 Apr, 28 Apr, 29 Apr).
IIA. Geophysical Activity Summary 25/2100Z to 26/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 434 km/s at 26/1939Z. Total IMF reached 6 nT at
26/1339Z. The maximum southward component of Bz reached -6 nT at
26/1326Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 225 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to isolated unsettled levels on days one, two, and three
(27 Apr, 28 Apr, 29 Apr).
