T. Kryachko, A. Samohvalov, S. Korotkiy and B.Satovskiy (Astrotel obs., KSU) report the discovery of an apparent supernova (mag approximately 18.5) on five unfiltered images with an exposure of 300 sec. (lim mag 21.0) obtained on oct. 29.75 UT with the Takahashi FRC-300 (D=300mm, F=2330mm) + CCD Apogee Alta U9000 at Kazan State University Astrotel observatory (Karachay-Cherkessia, Russia, MPCCOD: 114). The new object is located at R.A. = 01h04m46s.25 +/- 0".1, Decl. = +28d08'48".4 +/- 0".1 (equinox 2000.0), which is about 1,5" east and 4,0" north of the center of anonymous galaxy (R.A. = 01h04m46.14s, Decl = +28d08'44".4). Nothing is visible at this position on the Palomar Sky Survey (POSS-II red) obtained 1989-10-28 (via the Digitized Sky Survey; limiting mag 21.0) and on SDSS image. In MPChecker no asteroids.

T. Kryachko, A. Samohvalov, S. Korotkiy and B.Satovskiy (Astrotel obs., KSU) confirm this supernova on three unfiltered images with an exposure of 300 sec. (lim mag 21.0) obtained on Nov 3.77UT with the Takahashi FRC-300 (D=300mm, F=2330mm) + CCD Apogee Alta U9000 at Kazan State University station, Astrotel observatory (Karachay-Cherkessia, Russia, MPCCOD: 114). Please confirm this supernova matter, photographic and spectral! Confirm image: http://askh.ru.ru/images/Possible-SN-ac.jpg

PSN J01044625+2808484 2011.11.3.517 This possible supernova near PGC 1827548 was seen with 15 x 600 sec images using an infrared filter (>700 nm) Astrometry: RA 01 04 46.26 Dec 28 08 48.6 Photometry: 17.4 +/- 0.3 IR >700 nm These data were collected by Joseph Brimacombe, Coral Towers Observatory, Cairns, Australia Link to image and further information: http://www.flickr.com/photos/43846774@N02/6309992861/




2011 11 04.0961

PSN J01044625+2808484 not found on 3x300sec images, remotely taken on 2011 Nov. 04.0961UT using 0.45-m f/2.8 astrograph + unfiltered CCD (KAF09000) at ISON-NM Observatory (MPC H15). Perhaps, object can not be detected because of the large image scale (1.95"/pix). Limit magnitude ~20.4m. Image availeble at http://spaceobs.org/images/TOCP/PSNJ01044625+2808484.jpg Observer: L. Elenin, ISON-NM Observatory (remotely from Moscow), Mayhill, NM, USA.
