Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 221 Issued at 2200Z on 09 Aug 2015
IA. Analysis of Solar Active Regions and Activity from 08/2100Z to
09/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C4 event observed at
09/0752Z from Region 2396 (S17W24). There are currently 4 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (10 Aug, 11 Aug,
12 Aug).
IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z: 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
595 km/s at 09/0912Z. Total IMF reached 8 nT at 09/0441Z. The maximum
southward component of Bz reached -6 nT at 09/0320Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 2253 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to minor storm levels on day one (10 Aug), quiet to
active levels on day two (11 Aug) and quiet to unsettled levels on day
three (12 Aug).
