Prepared jointly by the U.S. Dept. of Commerce, NOAA,
Space Environment Center and the U.S. Air Force.
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 290 Issued at 2200Z on 17 Oct 2007
IA. Analysis of Solar Active Regions and Activity from 16/2100Z to 17/2100Z: Solar activity was very low.
IB. Solar Activity Forecast: Solar activity is expected to remain very low.
IIA. Geophysical Activity Summary 16/2100Z to 17/2100Z: The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled, with isolated active periods as a recurrent coronal hole becomes geoeffective. Isolated periods of minor storming may occur at high latitudes on day three (20 Oct) at the expected peak of the high-speed stream influence.
