Discovered by M. Tsuboi, Hiroshima, Japan, who discoverd on a frame (limit mag.= 16.4) taken taken on 2012 Oct. 18.856 UT using 0.30-m f/5.3 reflector + unfiltered CCD, which was confirmed as mag.= 15.3 on a composed frame taken on 2012 Oct. 19.741 UT under the limiting magnitude= 17.7.

This PSN was clearly seen in 180 seconds exposure images (V and Clear filter) with 43cm (F/6.3) telescope + FLI-PL6303E CCD camera at Mayhill, USA (T21, iTelescope.NET). I compared my imagses with DSS image. Magnitude is V=15.01. Position end figures are 34.02 and 29.01 (epoch 2000.0).

2012 10 20.48312

Mag.= 15.3 observed on Oct. 20.48312 UT remotely using 0.25-m f/3.4 hyperbolic astrograph + unfiltered CCD (SBIG ST-10XME) at RAS observatory near Mayhill, NM, U.S.A. (H06). Position and magnitude were measured on an image composed from 3-frames which were taken by each 120-seconds exposure under the limit magnitude = 19.0. Observer T. Yusa, Osaki, Japan. Position and magnitude was measured using UCAC-3 Link to images: http://www.palette.furukawa.miyagi.jp/space/images/2012/PSNin3344_121020.jpg




2012 10 20.7

Mag.= 14.7V, 14.6I observed by K. Yoshimoto, Yamaguti-ken, Japan, using 0.16-m f/6.3 reflector + Johnson-Cousins filter CCD (SBIG ST-9XEi). See an image at http://orange.zero.jp/k-yoshimoto/PSN%20J10433405+2453290.jpg.
