Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 158 Issued at 2200Z on 07 Jun 2010
IA.  Analysis of Solar Active Regions and Activity from  06/2100Z
to 07/2100Z:  Solar activity was very low. No significant flares were
observed during the past 24 hours.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low with a slight chance for a C-class event over the next 3 days
(8-10 June).
IIA.  Geophysical Activity Summary 06/2100Z to 07/2100Z:
The geomagnetic field was mostly quiet over the past 24 hours with
the exception of an isolated period of unsettled conditions between
06/21Z and 07/00Z.  The greater than 2 MeV electron flux at
geosynchronous orbit was at high levels during the past 24 hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be unsettled to active with an isolated period of minor
storming possible on day 1 (8 June). This activity is due to the
high speed stream from a coronal hole as well as a possible CME
arrival from a disappearing filament on 3 June. On day 2 (9 June)
the chance for active conditions early in the period exists.
Otherwise, mostly quiet to unsettled conditions are expected. 
Conditions are forecasted to return to quiet on day 3 (10 June).
