Notes
NOTE: SIMBAD already lists this star (2MASS J22373648+3436252) as type EB*, so it may be known after all - check the SIMBAD references.
Found automatically by hunt.py in TESS sector 16 (flagged in 1 sector(s)). Detection score 191.8.
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.
