Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 50 Issued at 2200Z on 19 Feb 2016
IA. Analysis of Solar Active Regions and Activity from 18/2100Z to
19/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
19/0508Z from old Region 2497 (N13, L=220). There are currently 3
numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be low on days
one, two, and three (20 Feb, 21 Feb, 22 Feb).
IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
636 km/s at 18/2112Z. Total IMF reached 5 nT at 19/1748Z. The maximum
southward component of Bz reached -4 nT at 18/2229Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 36465 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (20 Feb), quiet to unsettled
levels on day two (21 Feb) and quiet levels on day three (22 Feb).
