2008CBET.1429....1H

E. Y. Hsiao, M. L. Graham, C. J. Pritchet, and D. Balam, Department of Physics and Astronomy, University of Victoria, report that a spectrum (range 392-704 nm; resolution 0.3 nm) of 2008dx (cf. CBET 1427), obtained on June 28.33 UT with the 1.82-m Plaskett Telescope of the National Research Council of Canada, shows it to be a type-Ia supernova near maximum light. Cross-correlation with a library of supernova spectra using the "superfit" matching program of Howell et al. (2005, Ap.J. 634, 1190) indicates that 2008dx is most similar to the sub-luminous type-Ia supernova 1991bg near maximum light.
