This object was detected on my stacked images taken with 20cm Schmidt-Cassegrain telescope (F6.3) + Apogee Alta E47+ CCD camera (Exp. time were 15min, 5min, 5min in V, Rc, Ic band, respectively). Photometric results were V=14.92V, Rc=14.71, Ic=14.79 using TYC 6316-2147-1 as comparison star (V=11.66, B-V=0.138).

Mag.= 14.8, position end figures 10s.44, 26".0 observed by T. Noguchi, Chiba-ken, Japan, from a stocked frames (limit mag.= 17.5) exposed by 40-s x 4 using 0.23-m f/6.3 Schmidt-Cassegrain + unfiltered CCD (BITRAN BT-11E). Position and magnitude were measured from UCAC3. See an image at http://park8.wakwak.com/~ngc/images/TCPinSgr.jpg.

> http://www.k-itagaki.jp/images/sgr.jpg mag about 14.8, slightly declined from the first detection. A faint USNO-B1.0 star (r2mag = 19.55, position end figures 10s.450, 26".89) seems to be a quiescent counterpart.
