Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 116 Issued at 2200Z on 26 Apr 2018
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 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 (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 396 km/s at 26/1503Z. Total IMF reached 6 nT at
26/0940Z. The maximum southward component of Bz reached -4 nT at
25/2108Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 4623 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (27 Apr) and quiet levels on
days two and three (28 Apr, 29 Apr).
