Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 153 Issued at 2200Z on 02 Jun 2009
IA. Analysis of Solar Active Regions and Activity from 01/2100Z
to 02/2100Z: Solar activity was very low. Region 1019 (N28E15)
produced a B1 flare at 02/0639Z. This region retained its beta
magnetic configuration, with a slight decay in areal coverage.
IB. Solar Activity Forecast: Solar activity is expected to be very
IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z:
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet to unsettled, with isolated active levels at
high latitudes, on 03-04 June due to a recurrent corona hole high
speed stream. Quiet conditions are expected to return on 05 June.
