Summary of Changes

  • Plot colors aligned with NOAA G-Scales

    • The RTSW plot displays green columns for Kp <=4, then follows the G-Scales beginning with Kp = 5 (yellow)

  • Decimal Kp values displayed

    • After 8/4/2022, Kp values will now be displayed in decimal format (e.g., 1.33, 1.67, 2.00)
