The INTEGRAL/EINSTEIN/ROSAT/NVSS objects IGR J17418-12122, 2E 1739.1-1210, 1RXS J174155.3-121157 and NVSS J174155-121201 have recently been suggested to be the same and considered to be a microquasar candidate with likely counterparts at optical and IR wavelengths (Tsarevsky et al. 2004, ATEL #239; Bassani et al. 2004, ATEL #232). In order to establish the identity of these sources, a 10-min spectrum of the tentative optical counterpart USNO 0778-0495204 was acquired on March 26.5 2004 (UT) with the FAST spectrograph attached to the 1.5-m telescope at the F. L. Whipple Observatory.
