Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 230 Issued at 2200Z on 18 Aug 2015
IA. Analysis of Solar Active Regions and Activity from 17/2100Z to
18/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 3 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 on days one, two, and three (19 Aug,
20 Aug, 21 Aug).
IIA. Geophysical Activity Summary 17/2100Z to 18/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
638 km/s at 18/0017Z. Total IMF reached 6 nT at 18/2050Z. The maximum
southward component of Bz reached -4 nT at 18/2014Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 21632 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (19 Aug) and quiet levels on
days two and three (20 Aug, 21 Aug).
