Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 227 Issued at 2200Z on 15 Aug 2017
IA. Analysis of Solar Active Regions and Activity from 14/2100Z to
15/2100Z: 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
14/2210Z from Region 2671 (N11E73). 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, two, and three (16 Aug, 17 Aug, 18 Aug).
IIA. Geophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 477 km/s at 15/0052Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 1335 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (16 Aug), unsettled to minor
storm levels on day two (17 Aug) and quiet to minor storm levels on day
three (18 Aug).
