The Galactic Bulge Survey is a wide but shallow X-ray survey of regions aboveand below the Plane in the Galactic Bulge. It was performed using the ChandraX-ray Observatory's ACIS camera. The survey is primarily designed to find andclassify low luminosity X-ray binaries. The combination of the X-ray depth ofthe survey and the accessibility of optical and infrared counterparts makesthis survey ideally suited to identification of new symbiotic X-ray binaries inthe Bulge. We consider the specific case of the X-ray source CXOGBSJ173620.2-293338. It is coincident to within 1 arcsec with a very red star,showing a carbon star spectrum and irregular variability in the OpticalGravitational Lensing Experiment data. We classify the star as a late C-R typecarbon star based on its spectral features, photometric properties, andvariability characteristics, although a low-luminosity C-N type cannot be ruledout. The brightness of the star implies it is located in the Bulge, and itsphotometric properties overall are consistent with the Bulge carbon starpopulation. Given the rarity of carbon stars in the Bulge, we estimate theprobability of such a close chance alignment of any Galactic Bulge Surveysource with a carbon star to be <1e-3 suggesting that this is likely to be areal match. If the X-ray source is indeed associated with the carbon star, thenthe X-ray luminosity is around 9e32 erg/s. Its characteristics are consistentwith a low luminosity symbiotic X-ray binary, or possibly a low accretion ratewhite dwarf symbiotic.
