Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 58 Issued at 2200Z on 27 Feb 2018
IA. Analysis of Solar Active Regions and Activity from 26/2100Z to
27/2100Z: 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 slight chance for a C-class flare on day one (28 Feb) and
expected to be very low on days two and three (01 Mar, 02 Mar).
IIA. Geophysical Activity Summary 26/2100Z to 27/2100Z: The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 563 km/s at 27/1531Z. Total IMF
reached 11 nT at 27/1033Z. The maximum southward component of Bz reached
-9 nT at 27/1101Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 3341 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (28 Feb), quiet to unsettled
levels on day two (01 Mar) and quiet levels on day three (02 Mar).
