SN Ibn

0.03

OxQUB, Pan-STARRS

The spectrum reveals a blue continuum and narrow emission features identified as HeII 4686 and HeII 6560 and/or H-alpha, consistent with a redshift of z ~ 0.03. The combined photometry (see Astronote #2023-191 for details) indicates a fast-rising blue transient with a peak absolute mag Mg ~ -18.5 at this redshift. Together with the spectrum, we favour an Ibn classification.
