Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 162 Issued at 2200Z on 11 Jun 2007
IA. Analysis of Solar Active Regions and Activity from 10/2100Z to 11/2100Z: Solar activity was very low. Region 960 (S05W59) produced several B-class flares during the past 24 hours. The largest of these was a B8/Sf at 10/0027Z.
IB. Solar Activity Forecast: Solar activity is expected to be very low to low.
IIA. Geophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet on 12-13 June. Expect unsettled to active conditions, with isolated minor storm periods at high latitudes, on 14 June as a coronal hole rotates into a geoeffective position.
