Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 217 Issued at 2200Z on 04 Aug 2012
IA. Analysis of Solar Active Regions and Activity from 03/2100Z
to 04/2100Z: Solar activity was low. Region 1539 (S22E31) produced a
long duration C3/sf x-ray flare which began at 04/1104Z and ended at
04/1649Z. An associated limb event CME was observed in SOHO LASCO as
well as by STEREO coronagraphs, with an estimated speed of 905 km/s.
ENLIL depicts trajectory of the transient between Earth and STEREO
B, with a glancing blow expected beyond the forecast period. No new
active regions were numbered today.
IB. Solar Activity Forecast: Solar activity is expected to be low
with a slight chance for an isolated M-class over the next 3 days
(5-7 August).
IIA. Geophysical Activity Summary 03/2100Z to 04/2100Z:
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is
forecast to be primarily quiet over the next 3 days (5-7 August).
