TIC 1002554793
Eclipsing binaryProbably known
Notes
WARNING: same period as the known variable FASTT 578 53" away; the signal is probably its light leaking in.
NOTE: SIMBAD already lists this star (BD+01 2832) as type **, so it may be known after all - check the SIMBAD references.
Found automatically by hunt.py in TESS sector 23 (flagged in 1 sector(s)). Detection score 60.6.
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.
