TIC 161577376

Single dip / odd eventKnown to NASA (TOI)

Notes

Already known to NASA: CTOI 161577376.01 (PC). Already on NASA's TESS list as CTOI 161577376.01 (PC). NOTE: SIMBAD already lists this star (HD 272695) as type SB*, so it may be known after all - check the SIMBAD references. Found automatically by hunt.py in TESS sector 4 (flagged in 5 sector(s)). Detection score 73.1. 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.
