Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 159 Issued at 2200Z on 08 Jun 2010
IA. Analysis of Solar Active Regions and Activity from 07/2100Z
to 08/2100Z: Solar activity was very low.
IB. Solar Activity Forecast: Solar activity is expected to be very
low with a slight chance for a C-class event for the next 3 days
(9-11 June).
IIA. Geophysical Activity Summary 07/2100Z to 08/2100Z:
The geomagnetic field was mostly quiet with the exception of an
isolated unsettled period between 1500-1800Z. 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 mostly quiet to unsettled with an isolated period of
active conditions likely early on day 1 (9 June). Conditions are
forecast to be quiet on days 2 and 3 (10-11 June).
