Rare & notable finds

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

Already known: catalogued variable star nearby: Gaia DR3 1527437125197385984 (ROT, P = 28.632 d), 272" away. 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.

Checked, nothing found (9)

Notes

Probably noise or an instrument effect. Rare, already known: Lopsided transit (catalogued variable star nearby: Gaia DR3 1527437125197385984 (ROT, P = 28.632 d), 272" away). Found automatically by hunt.py in TESS sector 22 (flagged in 1 sector(s)). Detection score 110.5. 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.
