Scientific paper

Inspection of a noisy CCD spectrum (range 340-1000 nm), obtained on Nov. 7 UT with the 3-m Shane reflector (+ Kast) at Lick Observatory, reveals that CSS081009:002151-163204 (ATel#1823) has a blue continuum with superposed narrow emission lines at a redshift of 0.285. We do not detect any broad, supernova-like features, perhaps because of the relatively low signal- to-noise ratio. Either this object is an active galactic nucleus, or it is potentially a very luminous supernova, possibly similar to SN 2008es (Miller et al., arXiv:0808.2193; Gezari et al., arXiv:0808.2812).
