Abstract:
We present a sample of 209 variable objects - very likely optical
counterparts to the X-ray sources detected in the direction of the
Galactic center by the Galactic Bulge Survey (GBS) carried out with
the Chandra satellite. The variable sources were found in the
databases of the OGLE long term survey monitoring regularly the
Galactic bulge since 1992. The counterpart candidates were searched
based on the X-ray source position in the radius of 3.9 arcsec.
