Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 149 Issued at 2200Z on 28 May 2008
IA. Analysis of Solar Active Regions and Activity from 27/2100Z
to 28/2100Z: 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 27/2100Z to 28/2100Z:
The geomagnetic field was at mostly unsettled levels today. At about
27/2200Z, the ACE satellite detected a Solar Sector Boundary
crossing from a negative (toward) orientation to a positive (away)
orientation. At about 28/0130Z, a shock was detected at ACE with
subsequent sharp increases in both density and wind speed,
indicative of a co-rotating interaction region (CIR). The CIR was
followed by the onset of a high speed stream at about 28/0500Z;
solar wind velocities increased to about 525 km/s by the end of the
summary period. The greater than 2 MeV electron flux at
geosynchronous orbit reached high levels for a brief period today.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at quiet to unsettled levels, with a chance for
isolated active periods, during all three days of the forecast
period (29 May to 31 May) due to the high speed stream.
