Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 41 Issued at 2200Z on 10 Feb 2018
IA. Analysis of Solar Active Regions and Activity from 09/2100Z to
10/2100Z: 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
10/1321Z from Region 2699 (S07E01). 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 and a slight chance for an M-class
flare on days one, two, and three (11 Feb, 12 Feb, 13 Feb).
IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 409 km/s at 10/1847Z. Total IMF reached 10
nT at 10/0709Z. The maximum southward component of Bz reached -5 nT at
10/0319Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (11 Feb, 12 Feb, 13
Feb).
