Brightenings AnD Polarity Inversion Tracking (BADPIT) method for studying solar active region evolution before major solar flares

Alexander Nindos, Augustin Andr\'e-Hoffmann, Manolis K. Georgoulis, Marianna B. Kors\'os, Robertus Erd\'elyi, Spiros Patsourakos

The BADPIT method detects up to five times more EUV transient brightenings in flaring active regions than in non-flaring ones with similar sunspot types.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

both the power-law threshold method and the 3-(sigma) method can be useful diagnostic tools for distinguishing between imminent flaring or not, several hours before the onset of major solar flares.

C2weakest assumption

The assumption that the differences in detected transient brightenings between the two active regions are due to their flare productivity rather than other unaccounted factors, and that this will hold in a larger sample.

C3one line summary

The BADPIT method finds substantially more EUV transient brightenings in a flare-productive solar active region than in a quiescent one, potentially serving as an early indicator for major flares.
