*Instant class shows the estimated GOES-B flux level at each time — intended only as a quick user reference. Minor variations may occur between satellites due to calibration and instrument differences. For official flare magnitudes, see NOAA/SWPC listings.

Data source: NOAA SWPC – GOES XRS

GOES-08: 1995-01 → 2003-06 | GOES-10: 2003-07 → 2009-11 | GOES-14: 2009-12 → 2010-08

GOES-15: 2010-09 → 2017-06 | GOES-16: 2017-07 → 2025-04

Note: Fluxes from GOES-8 to 15 were rescaled (×0.85 A-band, ×0.70 B-band) to match the legacy NOAA/SWPC flare classification scale; GOES-16 uses its native calibration.
