Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 280 Issued at 2200Z on 06 Oct 2012
IA. Analysis of Solar Active Regions and Activity from 05/2100Z
to 06/2100Z: Solar activity has been at very low levels for the past
24 hours. Region 1585 (S20E12) has been the most active region
producing multiple B-class events. No Earth directed CME's were
observed in the past 24 hours.
IB. Solar Activity Forecast: Solar activity is expected to be at
very low to low levels for the next three days (07-09 October).
IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z:
The geomagnetic field has been at predominantly quiet levels for the
past 24 hours. Solar wind speeds, as measured by the ACE spacecraft,
remain at nominal levels, however energetic particle measurments by
the EPAM sensor, indicate a CME is currently traveling towards
Earth.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at predominantly quiet levels on day one (07
October). An increase to unsettled to active levels with a chance
for minor storm periods is expected on days two and three (08-09
October) as the 05 October CME is forecasted to arrive.
