Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 205 Issued at 2200Z on 24 Jul 2006

IA. Analysis of Solar Active Regions and Activity from 23/2100Z to 24/2100Z: Solar activity was low. A C1 flare occurred at 24/1501 UTC from a region on the east limb at approximately S12. No new regions were numbered today.

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

IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic field was mostly quiet.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled with possible active conditions on 25 July due to coronal hole activity. On 26 and 27 July, quiet to unsettled conditions are expected.
