Abstract: We present the results of the optical identification of hard X-ray sourceIGRJ18257-0707 trough the spectroscopic observations of its optical counterpartwith RTT150 telescope. Accurate position of the X-ray source, determined usingChandra observations, allowed us to associate this source with the faintoptical object m R=~20.4, which shows broad H \alpha emission line in itsoptical spectrum. Therefore we conclude that the source IGRJ18257-0707 is atype 1 Seyfert galaxy at redshift z=0.037.
