TIC 383669896
Eclipsing binaryProbably known
Notes
WARNING: same period as the known variable CSTAR n045656 34" away; the signal is probably its light leaking in.
NOTE: SIMBAD already lists this star (UCAC2 11973) as type EB*, so it may be known after all - check the SIMBAD references.
Found automatically by hunt.py in TESS sector 27 (flagged in 1 sector(s)). Detection score 336.5.
Not in VSX, ASAS-SN or ZTF variable catalogues at the time of the search; Gaia DR3 lists it as a variable-star candidate.
Unchecked by hand yet: verify the period, nearby stars and a wider catalogue search.
