POSSIBLE SUPERNOVA IN PGC 134795
     Ivica Pletikosa and Filip Novoselnik, on behalf of the "La Sagra Sky
Survey" (LSSS) supernova search team (which includes also Denis Vida, Ivica
Skokic, David Gostinski, Robert Gregic, Salvador Sanchez, Jaime Nomen, Reiner
Stoss, Bill Yeung, Juan Rodriguez, and Miguel Hurtado), report the discovery
of an apparent supernova (magnitude 17.3) on three CCD images (limiting mag
about 20.0) taken on Oct. 13.909, 13.923, and 13.936 UT with a 0.45-m
telescope.  The new object is located at R.A. = 1h55m18s.37, Decl. =
-17d46'46".3 (equinox 2000.0), which is 8".6 west and 6".2 south of the
nucleus of the presumed host galaxy, PGC 134795.  Additional approximate
magnitudes for the suspernova suspect, from unfiltered images unless
otherwise noted:  1996 Dec. 4.467, [22 (Digitized Sky Survey, red plate);
2010 Oct. 16.946, 17.9 (LSSS).  The LSSS image from Oct. 13 has been posted
(with the red DSS image on the right) at the following website URL:

Cairns, Australia, finds the new object at mag 18.2 (red mag 17.9 measured
by Vida from the same image) and position end figures 18s.29, 46".5 on a
stacked CCD exposure taken on Oct. 17.436 remotely using a 51-cm RCOS
telescope at the New Mexico Skies Observatory; Brimacombe's image is
