Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 228 Issued at 2200Z on 16 Aug 2018
IA. Analysis of Solar Active Regions and Activity from 15/2100Z to
16/2100Z: Solar activity has been at very low levels for the past 24
hours. There is currently 1 numbered sunspot region on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (17 Aug, 18 Aug, 19 Aug).
IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 512 km/s at 16/0128Z. Total IMF reached 13
nT at 16/1007Z. The maximum southward component of Bz reached -8 nT at
15/2106Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 391 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (17 Aug) and quiet levels
on days two and three (18 Aug, 19 Aug).
