M. Koishikawa, Sendai Astronomical Observatory, reports the discovery of an apparent supernova (mag 17.5) on a 180-s R-band exposure (limiting mag 19.0) taken on Nov. 6.580 UT with a 1.3-m f/4.85 reflector. The new object, which was found to be at mag 17.3 by Koishikawa on Nov. 6.608, is located at R.A. = 0:57:35.60 ± 0s.03, Decl. = -1:23:33.0 ± 0".5 (equinox 2000.0); nothing was visible at this position on his image of UGC 595 taken the previous night (Nov. 5.518; limiting mag 19.0). Koishikawa reports V = 17.4 on Nov. 10.562 for 2010jo. Koishikawa also reports that K. Itagaki obtained unfiltered confirming CCD images of 2010jo on Nov. 6.608 with a 0.60-m f/5.7 reflector, yielding mag 17.3 and position end figures 35s.58, 33".4 (which is offset 10" east and 6" south from the center of UGC 595). Itagaki's image is posted at website URL http://k-itagaki.jp/images/psn-ugc595.jpg. After posting on the Central Bureau's unconfirmed-objects webpage, C. Jacques and E. Pimentel (Belo Horizonte, Brazil) write that they obtained a 120-s unfiltered CCD image (limiting mag 17.8) on Nov. 7.02 remotely with a 43-cm f/6.8 reflector at the Gras Observatory in Nerpio, Spain; from this, they measured mag 16.8 and position end figures 35s.66, 33".6 – adding that nothing is visible at this position on a Digitized Sky Survey image from 1990 Aug. 28 (limiting red mag 19.0).
