Rare & notable finds

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

Already known: in SIMBAD as BD+69 653 (SB*); catalogued variable star nearby: Gaia DR3 1683351206909236224 (RS), 224" away. The rare-find check confirms what is on record - still nice, but not a new discovery.

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.

Checked, nothing found (9)

Notes

Probably noise or an instrument effect. Rare, already known: Lopsided transit (in SIMBAD as BD+69 653 (SB*); catalogued variable star nearby: Gaia DR3 1683351206909236224 (RS), 224" away). NOTE: SIMBAD already lists this star (BD+69 653) as type SB*, so it may be known after all - check the SIMBAD references. Found automatically by hunt.py in TESS sector 15 (flagged in 2 sector(s)). Detection score 318.8. 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.
