Discovered by K. Itagaki, Yamagata, Japan, on an unfiltered CCD frame using 0.50-m f/6.8 reflector at the Takanezawa station, Tochigi-ken, under the limiting magnitude= 18.5, which was confirmed on the frames taken during 20 mimutes after discovery. Nothing is visible at this location on his past frames and verifying was done on a frame (limit mag.= 19.0) taken on 2007 August 23.589 UT using 0.60-m f/5.7 reflector + unfiltered CCD at Yamagata, however no recent frame.

I took confirmation images of this PSN with 0.5m Astrograph+FLI ProLine PL11002M CCD camera at Mayhill, USA (T11, iTelescope.NET), remotely . I checked DSS2 image of NGC6667 using Aladine, Simbad. Photometry results were V=16.60 and Ic=16.06 using TYC 4430-18-1 as a comparison. My image avaiable at http://meineko.sakura.ne.jp/ccd/PSN_J18303179+6759297.jpg. Seiichiro Kiyota (Kamagaya, Japan)

Mag.= 17.1, position end figures 31s.82, 29".6 (refer to UCAC4 catalog) observed by T. Noguchi, Chiba-ken, Japan, on eight stacked 30-s frames (limit mag.= 17.5) with 0.23-m f/6.3 Schmidt-Cassegrain + unfiltered CCD , who informs an image posted at http://park8.wakwak.com/~ngc/images/PSNinNGC6667.jpg.

This possible supernova in NGC 6667 was detected with 6 x 10 min images using a clear filter Photometry: Mag 16.71 +/- 0.06 C (V for ref) Astrometry: RA 18 30 31.84 Dec +67 59 30.0 These data were collected remotely from New Mexico Skies, Mayhill, New Mexico, USA by Joseph Brimacombe, Coral Towers Observatory, Cairns, Australia.
