Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 152 Issued at 2200Z on 01 Jun 2009
IA. Analysis of Solar Active Regions and Activity from 31/2100Z
to 01/2100Z: Solar activity was very low. Region 1019 (N28E29)
developed into a Cro beta group with 13 spots and produced a B1
x-ray flare at 01/0807Z.
IB. Solar Activity Forecast: Solar activity is expected to be very
low, with a slight chance for a C-class flare from Region 1019.
IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z:
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet on 2 June. Quiet to unsettled levels, with
isolated active conditions at high latitudes, are expected on 3-4
June due to a recurrent coronal hole.
