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 180 Issued at 2200Z on 29 Jun 2001IA. Analysis of Solar Active Regions and Activity from 28-2100Z to 29-2100Z Solar activity was low with only a couple of weak
C-class x-ray flares. Region 9514 merged with Region 9513 (N21W25);
as a result, region number 9514 has been deleted. New Region 9523
(S48E35) was numbered today; it split off from Region 9518 (S47E22).
