Filip Novoselnik, on behalf of La Sagra Sky Survey Supernova Search Team (including also Denis Vida, Ivica Skokic, Robert Gregic, Salvador Sanchez, Jaime Nomen, Reiner Stoss, Bill Yeung, Juan Rodriguez, and Miguel Hurtado), reports the discovery of an apparent supernova (mag 17.0) on three CCD images (limiting magnitude about 20.0) taken on July 20.101, 20.116, and 20.132 UT with a 0.45-m telescope. The new object, which was also found at V = 18.0 in six stacked 90-s images taken at La Sagra with a 0.40-m telescope on July 16.091, is located at R.A. = 21:50:54.34, Decl. = -17:46:09.4 (equinox 2000.0), which is 6" west and 5" north of the nucleus of the galaxy PGC 190539. Nothing is present on a Digitized Sky Survey image from 1995 June 5 (limiting red mag 22).
