:Product: 0614RSGA.txt :Issued: 2008 Jun 14 2205 UTC # Prepared jointly by the U.S. Dept. of Commerce, NOAA, # Space Weather Prediction Center and the U.S. Air Force. # Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 166 Issued at 2200Z on 14 Jun 2008 IA. Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity was at very low levels. Region 998 (S10W01) decayed to spotless plage. IB. Solar Activity Forecast: Solar activity is expected to remain at very low levels. IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic field was at quiet to minor storm levels. A co-rotating interaction region was observed at the ACE spacecraft around 14/1200Z. Wind speeds began climbing soon thereafter to end the period at just below 550 km/s, with the interplanetary magnetic field Bz component ranging between +13 and -17 nT. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels for the forecast period (15 to 17 June). There is a chance for active conditions and a slight chance for isolated minor storm periods all three days due to a coronal hole high speed stream rotating into a geoeffective position. III.
