The operational data in the graph above has been modified to remove the scaling factor that has been applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor in the operational data, flare indices for the operational data were reported as 42% smaller than for the science quality data. The scaling factor has also been removed from the solar flare list to reflect the true physical units.
