Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 241 Issued at 2200Z on 29 Aug 2017
IA. Analysis of Solar Active Regions and Activity from 28/2100Z to
29/2100Z: 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
29/0300Z from Region 2674 (N11E70). 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 and a slight chance for an M-class
flare on days one, two, and three (30 Aug, 31 Aug, 01 Sep).
IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 1127 km/s at 28/2101Z. Total IMF reached 14
nT at 29/1945Z. The maximum southward component of Bz reached -10 nT at
29/1826Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 1628 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at unsettled to active levels on day one (30 Aug) and active to
minor storm levels on days two and three (31 Aug, 01 Sep).
