TIC 185881793
Eclipsing binaryProbably known
Notes
WARNING: same period as the known variable ASASSN-V J201116.40+422610.5 44" away; the signal is probably its light leaking in.
NOTE: SIMBAD already lists this star (UCAC4 663-088918) as type SB*, so it may be known after all - check the SIMBAD references.
Found automatically by hunt.py in TESS sector 15 (flagged in 2 sector(s)). Detection score 251.7.
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.
