Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 184 Issued at 2200Z on 02 Jul 2008

IA. Analysis of Solar Active Regions and Activity from 01/2100Z to 02/2100Z: Solar activity was very low. No flares occurred during the past 24 hours and the solar disk continues to be spotless.

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

IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic field was quiet during the past 24 hours.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet for the first day (03 July). An increase to mostly unsettled levels is expected late on the first day or on the second day (04 July) due to recurrence. Activity is expected to return to predominantly quiet levels on the third day (05 July).
