TIC 402066964
Eclipsing binaryProbably known
Notes
WARNING: same period as the known variable WISE J233040.9-660547 57" away; the signal is probably its light leaking in.
Found automatically by hunt.py in TESS sector 28 (flagged in 3 sector(s)). Detection score 101.0.
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.
