  I agree.  There is no bright candidate in DSS images on the reported
position; on the other hand, in USNO-B1.0 catalog, there is a fainter
star having some large proper motion, which is possibly near to the
reported position of new object on epoch 2003.6 : 

18:49:37.80 -09:33:51.5 (J2000.0, epoch=2000.0), r1mag=17.67,
  r2mag=19.08, imag=19.41, pmRA=-0.514 mas/yr, pmDecl = -22 mas/yr 

  Further examination is surely needed for the identification of the
quiesient counterpart.
