Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 152 Issued at 2200Z on 01 Jun 2001
IA. Analysis of Solar Active Regions and Activity from 31/2100Z
to 01/2100Z: Solar activity has been low. Three new regions were
numbered today as Region 9483 (S22W59), 9484 (S08E36), and 9485
(S23E75).
IB. Solar Activity Forecast: Solar activity is expected to be low.
IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z:
The geomagnetic field was quiet to unsettled.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet to unsettled. Isolated active conditions are
possible through the three day period due to a favorably positioned
coronal hole.
