Transit candidateRare, already known
Rare & notable finds
Something unusual, worth a look - less certain than a significant find. How these checks work →
Already known: in SIMBAD as TYC 4598-1217-1 (*); catalogued variable star nearby: Gaia DR3 2298672067393553664 (ROT), 145" away. The rare-find check confirms what is on record - still nice, but not a new discovery.
- Changing transit depth hint
The dip depth changes by 16% between transits - a disintegrating planet trailing dust, starspots, or light from another star mixing in. - 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: Changing transit depth; Lopsided transit (in SIMBAD as TYC 4598-1217-1 (*); catalogued variable star nearby: Gaia DR3 2298672067393553664 (ROT), 145" away).
Found automatically by hunt.py in TESS sector 19 (flagged in 5 sector(s)). Detection score 446.6.
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.
