Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 241 Issued at 2200Z on 29 Aug 2010
IA.  Analysis of Solar Active Regions and Activity from  28/2100Z
to 29/2100Z:  Solar activity has been at very low levels for the past
24 hours. Region 1101 (N12E07) remains quiet and stable. New Region
1102 (N27W13) was numbered today and emerged on the disk as a C-type
sunspot group with a beta magnetic classification.
IB.  Solar Activity Forecast:  Solar activity is expected to be at
very low levels for the next three days (30 August - 01 September).
IIA.  Geophysical Activity Summary 28/2100Z to 29/2100Z:
The geomagnetic field has been at quiet levels for the past 24 hours.
ACE solar wind readings indicated velocities gradually decreasing 
from 580 to 450 km/s during the period. This decrease in velocity
was associated with the waning effects of the latest coronal hole
high speed stream. The greater than 2 MeV electron flux at
geosynchronous orbit was at high levels throughout the period.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet levels for the next three days (30 August -
01 September).
