Abstract (from CDS):

G. Duszanowicz, Akersberga, Sweden, reports his discovery of a variable star of red magnitude 14.9 in Ursa Major (and located 159" west and 106" north of the center of the galaxy UGC 6628) on unfiltered CCD images (limiting mag 18.2) taken on Nov. 16.125, 18.018, and 19.018 UT with a 32-cm reflector. The variable object is located at R.A. = 11h39m50s.55, Decl. = +45d58'18".8 (equinox 2000.0); nothing is visible at this position on previous images taken by Duszanowicz (limiting magnitude ranging from 18.7 on 2007 Mar. 13.901 to 16.5 on 2008 Apr. 11, with poor sky conditions on the final date), though a star of red mag 19.3 (USNO-A2.0 catalogue 1350-07983055) is visible at this possition. An image of the variable has been posted by Duszanowicz at website URL http://moonbase.be/html/gallery/sncand/PGC36188-S001-STACK.jpg; this shows the variable to be identical with the apparent quasar discovered at mag 14.5 by J. Huchra at Palomar on 1975 Mar. 15 (and reported by Kowal et al. 1976, PASP 88, 521; photographs in Figure 3); the object faded quickly to mag 20 by 1975 Apr. 1. This object was then designated NSV 5285 in the General Catalogue of Variable Stars, apparently because spectroscopic observations of the outburst were lacking in 1975.
