Discovered by K. Itagaki, Yamagata, Japan, on an unfiltered CCD frame using 0.60-m f/5.7 reflector under the limiting magnitude= 19.5. PSN was confirmed on five followed-up frames after the discovery. His discovery image was posted at http://k-itagaki.jp/images/7371.jpg.

Mag.= 16.8, position end figures 05s.02, 48".2 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/PSNinNGC7371.jpg.

Mag.=16.6U, position end figures 05s.06, 48".4 (reference stars from UCAC-4), on three stacked 120-s frames (limit mag.= 19.0) using 0.43-m f/6.8 astrograph + SBIG STL-11000M camera at AstroCamp Observatory. Nerpio, Spain. Observer T. Yusa, Osaki, Japan. An image was posted at URL http://space.geocities.jp/yusastar77/supernova/PSNinN7371_150712.htm

2015 07 13.02760

This transient was observed on 2015 07 13.02760 by G. Masi, remotely using the 17"-f/6.8 robotic unit part of the Virtual Telescope Project facility, at Bellatrix Astronomical Observatory in Ceccano, Italy. 120-seconds exposures, unfiltered, show the source at mag. 17.0 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 05.04; 48.1 (J2000.0, mean residuals of 0.1" on both axes).
