2007mq CBET 1103 A. Sehgal, Osoyoos BC, L. Cox, Deep River ON and T. Puckett, Ellijay GA report the discovery of an apparent supernova (mag 19.6) (limiting mag 20.1) on a CCD image taken with a 0.60-m reflector, Ellijay, GA on Oct. 15.37 UT. in the course of the Puckett Observatory Supernova Search. The object is located at R.A. = 19h34m57s.90, Decl. = +87o16'33".6 (equinox 2000.0), which is 8".6 west and 2".6 north of UGC11495. The new object was confirmed at (mag 19.3)(limiting mag 19.9) Oct. 16.01 UT. by T. Orff, Shenandoah, PA. Nothing is visible at this location on images taken by Sehgal on 2007 Sep. 30 (limiting mag 20.0).
