Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 033 Issued at 2200Z on 02 Feb 2008
IA. Analysis of Solar Active Regions and Activity from 01/2100Z
to 02/2100Z: Solar activity was very low.
IB. Solar Activity Forecast: Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z:
The geomagnetic field ranged from quiet to minor storm levels. Active
to minor storm levels occurred between 01/2100Z and 02/0600Z,
followed by quiet to unsettled levels for the remainder of the
period. A high speed stream with wind speeds of approximately 580 to
620 km/s was responsible for the increase in geomagnetic activity.
The greater than 2 MeV electron flux at geosynchronous orbit was at
high levels today.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be mostly unsettled with isolated active periods on days
1 and 2 (03-04 February) as the high speed stream continues.
Conditions are expected to decline to quiet to unsettled levels on
day 3 (05 February).
