We can confirm the presence of a relatively bright counterpart at coordinates (scale 2.63"/pix):
R.A. = 17h39m50s.95 (+/-0.1223"), Decl. = -23o 50'01".10 (+/-0.2196") (equinox 2000.0; UCAC-2 catalogue reference stars).

Our multicolor photometry provides the following values: 2008, May. 26.457UT, V= +10.46, R= +10.01
