PSN J23194467+1011045   2013 10 07.4678*  23 19 44.67 +10 11 04.5  16.5 U   49E   2S  N7610     I 0



2013 10 07.468

Discovered by K. Itagaki, Yamagata, Japan, on a frame taken on 2013 October 7.468 UT using 0.50-m f/6.8 reflector + unfiltered CCD at Takanezawa station, Tochigi -ken, remotely under the limiting magnitude= 18.5. This PSN was confirmed on the following frames taken during one hour after discovery using same remote telescope. Itagaki writes nothing is visible at this location on his past frames including the most recent survey taken on 2013 Oct. 2.585 UT (limiting mag. = 18.0) using same remote telescope and of course no star on DSS (no limit mag. reported). Position and magnitude were measured from UCAC3 catalog. See a discovery image on http://www.k-itagaki.jp/images/7610.jpg.

I took confirmation images (120secx3 in V) of this PSN remotely with 0.32-m f/9.3 Ritchey-Chretien + SBIG ST8 XME CCD (T9, iTelescope.NET) at Siding Spring Observatory, Australia. Photometry result was V=16.39. My image are available at http://meineko.sakura.ne.jp/ccd/PSN_J23194467+1011045.jpg. Seiichiro Kiyota (Kamagaya, Japan)




2013 10 07.626

Mag.= 16.3, position end figures 44s.68, 04".8 observed by K. Kadota, Ageo, Saitama-ken, Japan, from a stacked twelve 90-s frames (limit mag.= 18.5) using 0.25-m f/5.0 reflector + unfiltered CCD. GSC-AT for position and Tycho-2 catalog (V mag.) for magnitude were adopted. from GSC-ACT. See an image at http://members.jcom.home.ne.jp/kenic-k/image/PSNinNGC7610-20131007.jpg.




2013 10 08.493

Mag.= 16.5, position end figures 44s.68, 04".7 observed by T. Noguchi, Chiba-ken, Japan, from sixteen stacked 40-s frames (limit mag.= 17.5) using 0.23-m f/6.3 Schmidt-Cassegrain + unfiltered CCD. Catalog UCAC4 was adopted to measure for position and magnitude. See a posted image at http://park8.wakwak.com/~ngc/images/PSNinNGC7610.jpg.

This possible supernova in NGC 7610 was detected with 4 x 15 min images using a clear filter Photometry: 16.15 +/- 0.32 C (V for ref) Astrometry: RA 23 19 44.63 Dec +10 11 04.4 These data were collected remotely by Joseph Brimacombe, Coral Towers Observatory, Cairns, Australia.

2013 10 10.830

This transient was observed on 2013 10 10.830 by Gianluca Masi, Francesca Nocentini and Patrick Schmeer, remotely using the 17" robotic unit part of the Virtual Telescope Project facility in Ceccano, Italy. Unfiltered images show a source at mag. 16.0 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 44.69s 04.5" (J2000.0, mean residuals of 0.15" on both axes).




2013 10 09.186

Follow-up This possible supernova in NGC 7610 was detected with 5 x 15 min images using a clear filter Photometry: 16.02 +/- 0.33 C (V for ref) Astrometry: RA 23 19 44.66 Dec +10 11 04.9 These data were collected remotely by Joseph Brimacombe, Coral Towers Observatory, Cairns, Australia.
