Rare & notable finds

Something unusual, worth a look - less certain than a significant find. How these checks work →

Already known: in SIMBAD as UCAC4 701-049460 (*); in the ATLAS variable-star catalogue (Heinze et al. 2018) as J121.6764+50.0942. The rare-find check confirms what is on record - still nice, but not a new discovery.

Lopsided transit hint
The end of the transit is deeper than the start: a dust tail (disintegrating planet), rings, a fast-spinning star, or a blend.

Notes

Probably noise or an instrument effect. Rare, already known: Lopsided transit (in SIMBAD as UCAC4 701-049460 (*); in the ATLAS variable-star catalogue (Heinze et al. 2018) as J121.6764+50.0942). Found automatically by hunt.py in TESS sector 20 (flagged in 1 sector(s)). Detection score 226.1. 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. Updates: 2026-10-11 Planet check: Probably noise or an instrument effect 2026-10-11 Rare-find check: Lopsided transit 2026-10-11 Found by the automatic search in TESS sector 20
