TIC 402894918
Eclipsing binaryProbably known
Notes
WARNING: same period as the known variable ASASSN-V J201100.67+710649.6 68" away; the signal is probably its light leaking in.
Found automatically by hunt.py in TESS sector 23 (flagged in 3 sector(s)). Detection score 46.7.
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.
