Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 157 Issued at 2200Z on 06 Jun 2007
IA. Analysis of Solar Active Regions and Activity from 05/2100Z to 06/2100Z: Solar activity was low. Region 960 (S07E11), now in decay, produced a C9/2f at 1725 UTC. The region has simplified in white light and h-alpha. Magnetically the region is now classified as beta-gamma. Otherwise, there is little of significance on the visible disk.
IB. Solar Activity Forecast: Solar activity is expected to persist at low levels. However, there is a reasonable chance of an isolated M-class flare from Region 960.
IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic field was quiet. Slow solar wind (approximately 340 km/s) is currently buffeting the magnetosphere. The GOES greater than 2 MeV energetic electron flux reached high levels once again.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet for the next three days.
