Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 196 Issued at 2200Z on 14 Jul 2008
IA. Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity was very low. The visible disk remained spotless.
IB. Solar Activity Forecast: Solar activity is expected to remain very low.
IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic field was quiet to unsettled. The recurrent coronal hole high speed stream remained geoeffective. Solar wind speed measured at the ACE spacecraft ranged from approximately 650 km/s to 730 km/s.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be unsettled on Day 1 (15 July), becoming quiet on Day 2 (16 July). Activity is expected to be quiet to unsettled on Day 3 (17 July).
