Notes
Probably noise or an instrument effect.
NOTE: SIMBAD already lists this star (UCAC4 655-054070) as type SB*, so it may be known after all - check the SIMBAD references.
Found automatically by hunt.py in TESS sector 22 (flagged in 1 sector(s)). Detection score 107.2.
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.
