Transit candidateProbably noise

Notes

Probably noise or an instrument effect. Found automatically by hunt.py in TESS sector 5 (flagged in 1 sector(s)). Detection score 245.6. 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: 2026-10-02 Gaia hints at a hidden companion star (RUWE 1.7) 2026-10-02 Planet check: Probably noise or an instrument effect 2026-10-02 Found by the automatic search in TESS sector 5
