Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 171 Issued at 2200Z on 19 Jun 2008
IA. Analysis of Solar Active Regions and Activity from 18/2100Z
to 19/2100Z: Solar activity was very low. No flares occurred during
the past 24 hours. Region 999 (S03E20) was quiet and stable.
IB. Solar Activity Forecast: Solar activity is expected to remain
very low.
IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z:
The geomagnetic field was mostly quiet. Solar wind velocity observed
at ACE showed a steady decline during the past 24 hours, with day
end speeds around 450 km/s. The greater than 2 MeV electron flux at
geosynchronous orbit was at high levels.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet to unsettled on the first day (20 June), and is
expected to be predominantly quiet for second and third days (20-21
June).
