Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 160 Issued at 2200Z on 09 Jun 2010
IA. Analysis of Solar Active Regions and Activity from 08/2100Z
to 09/2100Z: Solar activity was very low. Region 1078 (S21W60) has
grown in size and magnetic complexity over the past 24 hours.
IB. Solar Activity Forecast: Solar activity is expected to be very
low to low with a chance for a C-class event from Region 1078 during
the next 3 days (10-12 June).
IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z:
The geomagnetic field was quiet for the past 24 hours. 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
forecast to be mostly quiet with a chance for an isolated period of
unsettled conditions during the next 3 days (10-12 June).
