TIC 157209051
Eclipsing binaryProbably known
Notes
WARNING: same period as the known variable ASASSN-V J070212.14-363919.5 36" away; the signal is probably its light leaking in.
Found automatically by hunt.py in TESS sector 7 (flagged in 1 sector(s)). Detection score 1753.1.
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.
