摘要：

Positions of the candidates for the optical counterpart of the X-ray source in the globular cluster NGC 6712 have been determined using photographic plates, image tube films, and CCD and Photon-Counting-Camera frames. The positions were determined with respect to meridian circle observations and the PPM catalogue. The small differences of the order of 0.1'' between our positions of the star called S by Nieto et al. (1990) and the radio position of Machin et al. (1990) confirm earlier suggestions that this star is indeed the optical counterpart of the X-ray source in NGC 6712. In addition, a new optical position of the X-ray source M 15:AC211/X2127+119 is given.
