Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 186 Issued at 2200Z on 05 Jul 2010
IA. Analysis of Solar Active Regions and Activity from 04/2100Z
to 05/2100Z: Solar activity was very low. New Region 1086 (N18W53)
formed on the disk as a simple beta sunspot group. A CME was
observed lifting off behind the NE limb late in the period. SOHO
LASCO C2 imagery first observed this event at 05/1754Z, as well as
STEREO-B COR2 imagery shortly afterwards at 05/1810Z. The CME
appears to be associated with old Region 1082 (N27, L=305) due to
return on 10 July.
IB. Solar Activity Forecast: Solar activity is expected to remain
at very low levels.
IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z:
The geomagnetic field was quiet. The greater than 2 MeV electron
flux at geosynchronous orbit reached high levels during the past 24
hours.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at mostly quiet levels during the next three days (06
– 08 July).
