Methodology and limitations

Detection criteria, parameter definitions, and model applicability.

Detection and probability models

GOES classes use the absolute 1–8 Å peak flux. Δ class shows the increase above the local background. Flare candidates use local extrema; they are not the official NOAA event catalog. Fluence uses actual elapsed time, in J/m².

R describes polarity-inversion-line weighted flux; D describes polarity complexity. Nowcast percentages come from the existing UTOV_r lookup model. Its forecast horizon and calibration are not specified in this codebase. R and D estimates are shown separately.

Charts preserve peaks when reducing display points. Analysis and CSV downloads retain the native cadence. Data gaps are not interpolated.

“Current cycle” means the artifact matches the requested cache window. Observation and render times are separate. Older results remain visible with a freshness label.

References: NOAA classification glossary / SunPy / JSOC acquisition

Acquisition is scheduled. Cached results are rechecked every 60 s. Model estimates are not calibrated operational forecasts.
