Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 174 Issued at 2200Z on 23 Jun 2006

IA. Analysis of Solar Active Regions and Activity from 22/2100Z to 23/2100Z: Solar activity was very low. There are no spots currently visible on the solar disk. Two CMEs were observed off the east limb on LASCO imagery at 23/0930Z and 23/1406Z. Both appear to be backsided events.

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

IIA. Geophysical Activity Summary 22/2100Z to 23/2100Z: The geomagnetic field was quiet.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to remain quiet.
