Transit candidateRare, already known

Rare & notable finds

Something genuinely unusual turned up. Treat it as a lead: every one of these has ordinary explanations too, listed with each. How these checks work →

Already known: in SIMBAD as UCAC4 696-050151 (*); catalogued variable star nearby: Gaia DR3 1015614462466669440 (RS), 213" away. The rare-find check confirms what is on record - still nice, but not a new discovery.

Microlensing (rogue planet?) significant
A one-off, symmetric brightening at BTJD 2581.99 that fits the gravitational-lens shape better than a flare (Einstein time 0.7 h). Events this short can be made by a free-floating (rogue) planet passing in front of the star. Very rare in TESS data; scattered light and asteroids can mimic it.
Transit duration (TDV) hint
The transit length changes from one transit to the next beyond the errors - a sign of a wobbling orbit (moon) or a precessing orbit.
Lopsided transit hint
The start of the transit is deeper than the end: a dust tail (disintegrating planet), rings, a fast-spinning star, or a blend.

Notes

Probably noise or an instrument effect. Rare, already known: Microlensing (rogue planet?); Transit duration (TDV); Lopsided transit (in SIMBAD as UCAC4 696-050151 (*); catalogued variable star nearby: Gaia DR3 1015614462466669440 (RS), 213" away). Found automatically by hunt.py in TESS sector 21 (flagged in 1 sector(s)). Detection score 114.9. 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.
