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 2288686818186898688 (RS), 119" away. The rare-find check confirms what is on record - still nice, but not a new discovery.

Ultra-short-period planet notable
One orbit takes 10.2 hours - ultra-short-period planets are found around only ~0.5% of stars (if the signal is a real planet - it hasn't passed the planet check).
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: Ultra-short-period planet; Lopsided transit (catalogued variable star nearby: Gaia DR3 2288686818186898688 (RS), 119" away). Found automatically by hunt.py in TESS sector 22 (flagged in 10 sector(s)). Detection score 111.1. 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; Ultra-short-period planet 2026-10-11 Found by the automatic search in TESS sector 22
