Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 151 Issued at 2200Z on 30 May 2008
IA. Analysis of Solar Active Regions and Activity from 29/2100Z to 30/2100Z: Solar activity was at very low levels. The visible disk remained spotless.
IB. Solar Activity Forecast: Solar activity is expected to remain at very low levels.
IIA. Geophysical Activity Summary 29/2100Z to 30/2100Z: The geomagnetic field was at quiet to unsettled levels. Solar wind velocities peaked at 665 km/s at about 30/0400Z, and remained elevated between 550 - 600 km/s for the balance of the period.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels, with a chance for isolated active periods, during days one and two (31 May - 01 Jun). By day three (02 Jun), the geomagnetic field is expected to return to mostly quiet levels.
