Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 180 Issued at 2200Z on 29 Jun 2009
IA.  Analysis of Solar Active Regions and Activity from  28/2100Z
to 29/2100Z:  Solar activity was very low. No flares were detected.
The visible disk was spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 28/2100Z to 29/2100Z:
Geomagnetic field activity ranged from quiet to active levels.
Unsettled to active levels occurred until 29/0600Z, followed by
mostly quiet conditions. ACE solar wind observations indicated Earth
remained under the influence of a coronal hole high-speed stream.
Solar wind velocities gradually increased until around 29/1500Z
(peak 575 km/sec at 29/1501Z), then remained elevated for the rest
of the period. A period of sustained southward IMF Bz occurred until
around 29/0200Z (minimum -9 nT at 29/2102Z).
IIB.  Geophysical Activity Forecast:  Geomagnetic field activity is
expected to be at quiet to unsettled levels on day 1 (30 June).
Field activity is expected to decrease to mostly quiet levels during
days 2 - 3 (01 - 02 July) as the high-speed stream subsides.
