Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 229 Issued at 2200Z on 17 Aug 2017
IA. Analysis of Solar Active Regions and Activity from 16/2100Z to
17/2100Z: 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
with a chance for a C-class flares and a slight chance for an M-class
flare on days one and two (18 Aug, 19 Aug) and expected to be very low
with a chance for a C-class flares on day three (20 Aug).
IIA. Geophysical Activity Summary 16/2100Z to 17/2100Z: The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 594 km/s at 17/1851Z. Total IMF
reached 13 nT at 17/0733Z. The maximum southward component of Bz reached
-12 nT at 17/0820Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 330 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at unsettled to minor storm levels on day one (18 Aug), quiet to
active levels on day two (19 Aug) and unsettled to active levels on day
three (20 Aug).
