Notes

WARNING: same period as the known variable V0432 Aur 57" away; the signal is probably its light leaking in. Found automatically by hunt.py in TESS sector 19 (flagged in 1 sector(s)). Detection score 2461.8. 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 1.6) 2026-10-11 Found by the automatic search in TESS sector 19
