Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 322 Issued at 2200Z on 18 Nov 2010
IA.  Analysis of Solar Active Regions and Activity from  17/2100Z
to 18/2100Z:  Solar activity was very low. Visible active regions
remained stable and quiet.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 17/2100Z to 18/2100Z:
The geomagnetic field was quiet. Solar wind  speed has increased to
about 550 km/s over the past 24 hours. Observations suggest that
this increase is in response to a high-speed stream associated with
coronal hole number 78 in the northwest hemisphere. 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.
