This is a confirmation observation by K. Itagaki (Yamagata, Japan) with a 0.60-m refl. + CCD. The object was discovered just before the confirmation during a survey program performed by himself and H. Kaneda (Sapporo, Japan) using a 0.21-m telescope. There is a faint (rmag about 19, bmag about 20) catalogued object at the reported position. Kaneda further noted that the ASAS-3 database suggests that the object was bright (mag around 13) on 2005 Aug. 4, 7, and 10.

Mag. 13.7U, R.A.=23h13m08.13s Decl.=+23d37m01.6s. Position and magnitude are measured on an image composed from 4-frames which were taken by each 60-seconds exposure under the limiting magnitude =17 remotely using 0.25-m f/3.4 reflector, GRAS, Mayhill (H06), T. Yusa, Osaki. Position and magnitude was measured using USNO-B1.0 Image: http://www.palette.furukawa.miyagi.jp/space/images/TCP110621.jpg
