Notes

Found automatically by hunt.py in TESS sector 17 (flagged in 1 sector(s)). Detection score 1433.4. 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: 2026-10-10 Gaia hints at a hidden companion star (RUWE 3.1) 2026-10-10 Found by the automatic search in TESS sector 17
