Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 111 Issued at 2200Z on 20 Apr 2016
IA. Analysis of Solar Active Regions and Activity from 19/2100Z to
20/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
19/2302Z from Region 2529 (N10W81). There are currently 2 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 (21
Apr, 22 Apr, 23 Apr).
IIA. Geophysical Activity Summary 19/2100Z to 20/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 391 km/s at 20/1928Z. Total IMF reached 9 nT at
20/1045Z. The maximum southward component of Bz reached -7 nT at
20/0639Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 310 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (21 Apr, 22 Apr) and quiet to
active levels on day three (23 Apr).
