Supernova 1954ad in UGC 4467
Abstract
J. Mueller reports her discovery on prints from the first Palomar Sky Survey of an apparent supernova (mag about 17.5) in UGC 4467 (R.A. = 8h30m.2, Decl. = +0 24', equinox 1950.0). The object is 6".7 west and 5".4 south of the galaxy's center. The plates were taken 1954 Dec. 21 UT by R. G. Harrington. No image appears at the position to a limiting mag of B about 21 on a plate taken by Mueller and J. D. Mendenhall on 1991 Jan. 19 with the 1.2-m Oschin Telescope in the course of the second Palomar Sky Survey. CCD images with a Gunn R filter obtained by S. Staples with the Palomar 1.5-m telescope show no image at the position to limiting mag about 21.5.
