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 153 Issued at 2200Z on 02 Jun 2009IA. 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
low.
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.
