Supernova 2010eb in NGC 488

Further to CBET 2321 and 2323, D. Milisavljevic, R. Fesen, and J. Parrent, Dartmouth College, report on low-resolution spectra (range 440-800 nm) of SN 2010eb obtained during morning twilight with the 2.4-m Hiltner telescope (+ CCDS) at the MDM Observatory on June 13.47 UT. Inspection of these spectra show that 2010eb appears to be a spectroscopically peculiar, sub-luminous type-Ia supernova. The spectra most closely resemble that of SN 1998bp (Matheson et al. 2008, A.J. 135, 1598) at approximately two weeks after maximum light.
