NED Abstract

2002IAUC.7875A...1A Circular No. 7875 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION SUPERNOVA 2002ce IN NGC 2604 R. Arbour, South Wonston, Hants., England, reports his discovery of an apparent supernova roughly 16" west and 12" south of the nucleus of the barred-spiral galaxy NGC 2604. The object, of mag 16.0-16.5, was found on an unfiltered CCD image obtained with a 0.3-m f/6.3 Schmidt Cassegrain and Starlight Xpress CCD camera on Apr.10.878 UT and confirmed on Apr. 11.863. The object's existence was also confirmed on Apr. 10.909 and 11.838 by T. Boles, Coddenham, Suffolk, who gave the position as R.A. = 8h33m22s.1, Decl. = +29d32'01"(equinox 2000.0). Arbour notes that the object was not present on his image of the region on Apr. 5.200, and it is also absent on the second-generation Digitised Sky Survey. T. Matheson, S. Jha, P. Challis and R. Kirshner, Harvard-Smithsonian Center for Astrophysics, report that a spectrum (range 370-750 nm), obtained by P. Berlind on Apr. 12.18 UT with the F. L. Whipple Observatory 1.5-m telescope (+ FAST spectrograph), shows it to be a type II supernova near maximum. The spectrum consists of a blue continuum with P-Cyg lines of hydrogen. Adopting the NASA/IPAC Extragalactic Database recession velocity of 2094 km/s for the host galaxy, the expansion velocity derived from the minimum of the H-beta line is 5300 km/s. 2002 April 12 (7875) Brian G.
