Notes

Found automatically by hunt.py in TESS sector 20 (flagged in 2 sector(s)). Detection score 528.5. Not in VSX, ASAS-SN or ZTF variable catalogues at the time of the search; not in Gaia DR3's variable lists. Unchecked by hand yet: verify the period, nearby stars and a wider catalogue search. Updates: 2026-10-11 Gaia hints at a hidden companion star (RUWE 3.2) 2026-10-11 Found by the automatic search in TESS sector 20
