Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 202 Issued at 2200Z on 20 Jul 2008
Analysis of Solar Active Regions and Activity from 19/2100Z
to 20/2100Z: Solar activity was at very low levels. Region 1000
(S12W05) remained quiet and stable.
Solar Activity Forecast: Solar activity is expected to remain
at very low levels.
Geophysical Activity Summary 19/2100Z to 20/2100Z:
The geomagnetic field was quiet. The greater than 2 MeV electron
flux at geosynchronous orbit reached high levels again today.
Geophysical Activity Forecast: The geomagnetic field is
expected to be mostly quiet to unsettled all three days of the
forecast period (21 - 23 July) with isolated active periods possible
on day three. The forecasted increase in activity is a result of a
recurrent coronal hole high speed stream that is expected to rotate
into a geoeffective position.
