Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 307 Issued at 2200Z on 03 Nov 2009
IA. Analysis of Solar Active Regions and Activity from 02/2100Z
to 03/2100Z: Solar activity was very low. The SOHO/LASCO imagery
observed a slow coronal mass ejection (CME) off the southwest limb
at 0501 UTC on 31 October. The CME appears to be earth directed
with a plane-of sky speed of 380 km/s.
IB. Solar Activity Forecast: Solar activity is expected to be low.
IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z:
Geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet on day 1 (4 November). Unsettled conditions
are expected on day 2 (5 November) due to possible effects from the
CME observed on 31 October. Quiet levels are expected to return on
day 3 (6 November).
