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 TYC 4306-1433-1 (*); catalogued variable star nearby: ZTF J000546.19+734759.3 (EW, P = 0.36591 d), 209" 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.
Single transit of another planet significant
Besides the known planet: the dip is not alone: 3 similar dips at regular intervals (first at BTJD 3638.55) - a periodic transit worth a full planet check.

Checked, nothing found (10)

Microlensing (rogue planet?) · Exocomet-shaped dip · Habitable zone & size · Transit timing (TTV) · Transit duration (TDV) · Changing transit depth · Dimming beside the transit · Trojan companions (L4/L5) · Self-lensing binary · Type of star

Notes

Probably noise or an instrument effect. Rare, already known: Lopsided transit; Single transit of another planet (in SIMBAD as TYC 4306-1433-1 (*); catalogued variable star nearby: ZTF J000546.19+734759.3 (EW, P = 0.36591 d), 209" away). Found automatically by hunt.py in TESS sector 24 (flagged in 4 sector(s)). Detection score 232.5. 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: Single transit of another planet; Lopsided transit 2026-10-11 Found by the automatic search in TESS sector 24
