Rare & notable finds

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

Already known: in SIMBAD as UCAC4 526-052621 (*); catalogued variable star nearby: ASAS J104818+1502.6 (DSCT, P = 0.18971 d), 162" 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.
Transits of a giant star notable
Gaia places this star among the giants: planets transiting giants are rare, and a big star makes even a large planet's dip tiny.

Checked, nothing found (7)

Microlensing (rogue planet?) · Exocomet-shaped dip · Habitable zone & size · Transit timing (TTV) · Transit duration (TDV) · Changing transit depth · Dimming beside the transit

Notes

Probably noise or an instrument effect. Rare, already known: Lopsided transit; Transits of a giant star (in SIMBAD as UCAC4 526-052621 (*); catalogued variable star nearby: ASAS J104818+1502.6 (DSCT, P = 0.18971 d), 162" away). Found automatically by hunt.py in TESS sector 22 (flagged in 1 sector(s)). Detection score 131.6. 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; Transits of a giant star 2026-10-11 Found by the automatic search in TESS sector 22
