Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 188 Issued at 2200Z on 07 Jul 2010
IA. Analysis of Solar Active Regions and Activity from 06/2100Z
to 07/2100Z: Solar activity was very low during the past 24 hours.
IB. Solar Activity Forecast: Solar activity is expected to remain
very low for the next three days (08 – 10 July).
IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z:
The geomagnetic field was quiet. The greater than 2 MeV electron
flux at geosynchronous orbit reached high levels during the past 24
hours.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet for day one (08 July). Quiet to unsettled,
with isolated active periods, are expected on days two and three (09
– 10 July) due to a recurrent coronal hole high speed stream
forecasted to become geoeffective.
