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 158 Issued at 2200Z on 07 Jun 2001IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z Solar activity was low. Isolated, mostly minor C-class
events occurred during the period. The largest event was an
impulsive, optically uncorrelated C6 flare that occurred at 07/2007
UTC. Most of the day's activity came from Regions 9484 (S06W47),
9488 (S18E04), and 9492 (N19E50). Region 9488 remains the most
magnetically complex region with a beta-gamma magnetic
classification. The rest of the disk and limbs were mostly quiet and
stable.
IB. Solar Activity Forecast
Solar activity is expected to be
mostly low. A slight chance of isolated M-class is possible.
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
The geomagnetic field was at quiet to mostly unsettled conditions.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet to unsettled conditions.
