Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 188 Issued at 2200Z on 07 Jul 2011
IA.  Analysis of Solar Active Regions and Activity from  06/2100Z
to 07/2100Z:  Solar activity was low during the past 24 hours. Region
1243 (N16W59) produced a C1 event at 07/0243Z. New Region 1245
(N15E58) was numbered overnight and is classified as a Cso-beta type
group. Both regions produced several B-class events.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low for the next three days (08-10 July).
IIA.  Geophysical Activity Summary 06/2100Z to 07/2100Z:
The geomagnetic field was mostly quiet during the past 24 hours. The
greater than 2 MeV electron flux at geosynchronous orbit reached
high levels during the period.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be mostly quiet on day one (08 July). Quiet to unsettled
conditions with a chance for isolated active periods are expected on
day two (09 July) due to the effects of a recurrent coronal hole
high speed stream (CH HSS). Conditions are expected to be mostly
quiet on day three (10 July) as the effects from the CH HSS subside.
