TIC 155990990
Transit candidateProbably known


Notes
Probably noise or an instrument effect.
WARNING: same period as the known variable ASASSN-V J002954.95-484948.0 66" away; the signal is probably its light leaking in.
Found automatically by hunt.py in TESS sector 29 (flagged in 2 sector(s)). Detection score 65.5.
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.
