Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 166 Issued at 2200Z on 15 Jun 2007

IA. Analysis of Solar Active Regions and Activity from 14/2100Z to 15/2100Z: Solar activity was very low. The visible solar disk remains spotless.

IB. Solar Activity Forecast: Solar activity is expected to be very low.

IIA. Geophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic field ranged from quiet to active. The solar wind speed has been decreasing through the day, but remains slightly elevated due to the coronal hole high speed stream.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet throughout the forecast period.
