Hello, Apparently IGR J17464-3213's position is quite close to the catalogued position of the black-hole candidate transient H1743-322. In fact, there were more candidate positions for H1743-322, and one of them seems to be consistent with IGR J17464-3213 (I got this info from Ada Paizis at the ISDC, Geneva Switzerland). If there's a new optical object in your FOV, than it would be very interesting to report this as an Astronomical Telegram or IAU Circular, since, to my knowledge, there has been no report of an optical counterpart of H1743-322 (or IGR J17464-3213).
