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 2006IA. Analysis of Solar Active Regions and Activity from 31-2100Z to 01-2100Z Solar activity was very low.
IB. Solar Activity Forecast
Solar activity is expected to remain
very low.
IIA. Geophysical Activity Summary 31-2100Z to 01-2100Z
The geomagnetic field was quiet to active. Solar wind speed has been
steadily increasing over the past 24 hours, rising from
approximately 400 km/s to approximately 550 km/s, indicating the
onset of the coronal hole high speed stream.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be unsettled to active on 02 - 03 June with possible
minor storm periods due to the coronal hole high speed stream.
Expect quiet to unsettled conditions on 04 June.
