Mag.=13.9, R.A.=10 25 07.42 Decl=+17 09 14.4 (UCAC3), remotely using a 0.43-m f/4.4 reflector + CCD (FLI ProLine EV2 CCD47-10-1-109) at the AstroCamp Observatory. Nerpio, Spain (I89). Position and magnitude were measured on an image composed from 3-frames which were taken by each 60-seconds exposure under the limiting magnitude = 16.5. Observer T. Yusa, Osaki, Japan.

R-band mag = 15.57 +/- 0.01 by Hidetaka Sato, Ota-ku, Tokyo, Japan. Position end figures 07s.40, 14".4 (USNO-A2.0), remotely using 0.43-m f/4.5 reflector + CCD (EV2 CCD47-10-1-109) at iTelescope Astrocamp Observatory, Nerpio, Spain (MPC-I89). The position and magnitude were measured on two images of 60 seconds of exposure under 17.0 R of the limiting magnitude at 1.3 of airmass. The standard stars were taken on Landolt SA98-666, 670, 671 and 685 at 1.5 of airmass.
