Notes

NOTE: SIMBAD already lists this star (HD 309050) as type SB*, so it may be known after all - check the SIMBAD references. Found automatically by hunt.py in TESS sector 10 (flagged in 1 sector(s)). Detection score 373.3. 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.
