Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 53 Issued at 2200Z on 22 Feb 2017
IA. Analysis of Solar Active Regions and Activity from 21/2100Z to
22/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C4 event observed at
22/1327Z from Region 2638 (N19E35). 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 (23 Feb,
24 Feb, 25 Feb).
IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 469 km/s at 22/0441Z. Total IMF reached 9
nT at 22/1302Z. The maximum southward component of Bz reached -6 nT at
22/1451Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 719 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to minor storm levels on day one (23 Feb), quiet to
active levels on day two (24 Feb) and quiet to unsettled levels on day
three (25 Feb).
