Notes
NOTE: SIMBAD already lists this star (HD 32505) as type SB*, so it may be known after all - check the SIMBAD references.
Found automatically by hunt.py in TESS sector 32 (flagged in 1 sector(s)). Detection score 2852.6.
Not in VSX, ASAS-SN or ZTF variable catalogues at the time of the search; not in Gaia DR3's variable lists.
