TIC 180652621

Single dip / odd eventKnown to NASA (TOI)

Notes

Already known to NASA: CTOI 180652621.01 (PC). Already on NASA's TESS list as CTOI 180652621.01 (PC). NOTE: SIMBAD already lists this star (TYC 2541-540-1) as type SB*, so it may be known after all - check the SIMBAD references. Found automatically by hunt.py in TESS sector 22 (flagged in 1 sector(s)). Detection score 104.3. 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.
