2015 02 10.636

Discovered by K. Itagaki, Yamagata, Japan, on 2015 February 10.636 UT using 0.35-m f/11 reflector remotely at Takanezawa station, Tochigi-ken under the limiting magnitude= 19.5, who writes nothing is visible at this location on the past frames including the recent frames in 2015 (but not so deep magnitude) and verifying was done on a frame (limiting mag.= 19.5) taken on 2006 November 24.696 UT using 0.60-m f/5.7 reflector at Yamagata.

I confirm the presence of this PSN (mag.+18.0) from several unfiltered images taken by 0.35m. Sch.-Cass. F/5.5 + SXVR H-9 CCD camera;40 sec. exposure; limit mag.+19.5; Giancarlo Cortini (Monte Maggiore Observatory-Predappio-ITALY).

I took confirmation images of this PSN with 0.61m astrograph and FLI PL-9000 CCD camera at Sierra Remote Observatory site of iTelescope.NET, CA, USA, remotely. Photometry results were V=18.14 and Ic=17.42. Potion end figures were 27.46 and 41.25 in R.A. and Dec. My image is available at http://meineko.sakura.ne.jp/ccd/PSN_J09132750+7627410.jpg.

2015 02 11.15117

Mag.=17.7U, position end figures 27s.37, 40".7, on an image composed from 3-frames which were taken by each 180-seconds exposure under the limiting magnitude = 19.5, remotely using a 0.50-m f/6.8 astrograph + CCD(FLI ProLine PL11002M) + f/4.5 focalreducer at the iTelescopeNET Mayhill, New Mexico, USA. Offset of the supernova from the galaxy center is 54" W, 51" S. Observer T. Yusa, Osaki, Japan. An image was posted at URL http://space.geocities.jp/yusastar77/supernova/PSNinN2748_150211.htm




2015 02 11.435

Mag.= 17.8, position end figures 27s.54, 41".0 observed by T. Noguchi, Chiba-ken, Japan, using 0.23-m f/6.3 Schmidt Cassegrain + unfiltered CCD. An image at http://park8.wakwak.com/~ngc/images/PSNinNGC2748.jpg.
