Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 226 Issued at 2200Z on 14 Aug 2017
IA. Analysis of Solar Active Regions and Activity from 13/2100Z to
14/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
14/1046Z. There are currently 1 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 (15 Aug,
16 Aug, 17 Aug).
IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 636 km/s at 13/2107Z. Total IMF reached 5 nT at
13/2257Z. The maximum southward component of Bz reached -3 nT at
13/2347Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 1017 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (15 Aug), quiet to active levels on day
two (16 Aug) and unsettled to minor storm levels on day three (17 Aug).
