Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 239 Issued at 2200Z on 27 Aug 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
on days one, two, and three (28 Aug, 29 Aug, 30 Aug).
IIA. Geophysical Activity Summary 26/2100Z to 27/2100Z: The geomagnetic
field has been at quiet to major storm levels for the past 24 hours.
Solar wind speed reached a peak of 666 km/s at 27/1730Z. Total IMF
reached 7 nT at 27/1607Z. The maximum southward component of Bz reached
-6 nT at 27/1627Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 39767 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (28 Aug) and quiet to
unsettled levels on days two and three (29 Aug, 30 Aug).
