Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 219 Issued at 2200Z on 07 Aug 2010
IA. Analysis of Solar Active Regions and Activity from 06/2100Z
to 07/2100Z: Solar activity was moderate. Region 1093 (N10E30)
produced an M1/2f flare at 07/1824Z. Associated with this event were
Tenflare signatures at 07/1827Z (110 sfu) and 07/1901Z (150 sfu)
along with Type II (675 km/s) and Type IV radio sweeps.
IB. Solar Activity Forecast: Solar activity is expected to be very
low to low with C-class flares likely from Region 1093 and 1095
(S18E19). A chance of M-class activity is possible from Region 1093.
IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z:
Geomagnetic field activity was quiet.
IIB. Geophysical Activity Forecast: Geomagnetic field activity is
expected to be mostly quiet with an isolated chance of unsettled
levels during the next three days (08 – 10 August).
