Transit candidateRare, already known

Rare & notable finds

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

Already known: in SIMBAD as 2MASS J13554390+6430113 (*); in the ATLAS variable-star catalogue (Heinze et al. 2018) as J208.9327+64.5032. 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 2MASS J13554390+6430113 (*); in the ATLAS variable-star catalogue (Heinze et al. 2018) as J208.9327+64.5032). Found automatically by hunt.py in TESS sector 14 (flagged in 4 sector(s)). Detection score 324.3. 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.
