Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 240 Issued at 2200Z on 28 Aug 2018
IA. Analysis of Solar Active Regions and Activity from 27/2100Z to
28/2100Z: 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 (29 Aug, 30 Aug, 31 Aug).
IIA. Geophysical Activity Summary 27/2100Z to 28/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 626 km/s at 27/2114Z. Total IMF reached 6
nT at 28/0052Z. The maximum southward component of Bz reached -4 nT at
28/1025Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 97630 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (29 Aug, 30 Aug)
and quiet levels on day three (31 Aug).
