Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 153 Issued at 2200Z on 01 Jun 2008

IA. Analysis of Solar Active Regions and Activity from 31/2100Z to 01/2100Z: Solar activity was very low.

IB. Solar Activity Forecast: Solar activity is expected to be very low.

IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z: The geomagnetic field was at quiet levels. Solar wind velocities were averaging around 560 km/s under the continued influence of the coronal hole high speed stream.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled conditions for day one (02 Jun). Quiet levels are expected for days two and three (03-04 June) as the influence of the high speed stream is expected to wane.
