Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 52 Issued at 2200Z on 21 Feb 2017
IA. Analysis of Solar Active Regions and Activity from 20/2100Z to
21/2100Z: 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 chance for a C-class flares on days one, two, and three (22 Feb,
23 Feb, 24 Feb).
IIA. Geophysical Activity Summary 20/2100Z to 21/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 486 km/s at 20/2149Z. Total IMF reached 6 nT at
21/2049Z. The maximum southward component of Bz reached -4 nT at
21/0325Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 1109 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on days one and three (22 Feb, 24 Feb)
and unsettled to minor storm levels on day two (23 Feb).
