NED Abstract

2000IAUC.7535A...1M Circular No. 7535 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION SUPERNOVA 2000ez IN NGC 3995 T. Matheson, S. Jha, P. Challis, and R. Kirshner, Harvard- Smithsonian Center for Astrophysics, report that spectra of SN 2000ez (cf. IAUC 7533), obtained by J. Huchra on Dec. 3.49 UT with the F. L. Whipple Observatory 1.5-m telescope (+ FAST spectrograph) and by N. Caldwell on Dec. 3.53 with the MMT 6.5-m telescope (+ Blue Channel spectrograph), show it to be a type-II supernova several days after maximum light. The spectra consist of a continuum with superposed P-Cyg lines of H, He, and Ca II. Adopting the NASA/IPAC Extragalactic Database recession velocity of 3254 km/s for the host galaxy, the expansion velocity derived from the minimum of the H-beta line is 4000 km/s. 2000 December 4 (7535) Daniel W. E. Green
