Solar activity report
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 152 Issued at 2200Z on 01 Jun 2001IA. 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.
