Rare & notable finds

A notable find: not unheard of, but the kind of system astronomers are glad to have more of. How these checks work →

Already known: in SIMBAD as TYC 4361-46-1 (SB*); catalogued variable star nearby: Gaia DR3 1108498696521056896 (ROT, P = 4.2273 d), 241" away. The rare-find check confirms what is on record - still nice, but not a new discovery.

Superflare notable
A flare releasing roughly 8.1e+34 erg (rough, from TESS's band) on a Sun-like star - a 'superflare', more than 10x the biggest flare ever seen on the Sun.

Notes

Notable, already known: Superflare (in SIMBAD as TYC 4361-46-1 (SB*); catalogued variable star nearby: Gaia DR3 1108498696521056896 (ROT, P = 4.2273 d), 241" away). NOTE: SIMBAD already lists this star (TYC 4361-46-1) as type SB*, so it may be known after all - check the SIMBAD references. Found automatically by hunt.py in TESS sector 20 (flagged in 1 sector(s)). Detection score 1830.3. 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 Rare-find check: Superflare 2026-10-11 Found by the automatic search in TESS sector 20
