Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 161 Issued at 2200Z on 10 Jun 2010
IA.  Analysis of Solar Active Regions and Activity from  09/2100Z
to 10/2100Z:  Solar activity has been at very low levels for the past
24 hours. New Region 1080 (S25W39) was numbered early in the period
today and is a beta magnetic classification. Region 1078 (S22W73)
remained stable throughout the period.
IB.  Solar Activity Forecast:  Solar activity is expected to be at
very low levels with a slight chance for C-class events.
IIA.  Geophysical Activity Summary 09/2100Z to 10/2100Z:
The geomagnetic field has been at quiet levels for the past 24 hours.
Observations made from the ACE spacecraft indicated the arrival of a
weak coronal hole high-speed stream, with an increase in solar wind
speeds from 305 km/s to 461 km/s. 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 at quiet levels for the next three days (11-13 June).
