Description
We have been regularly monitoring the outburst decay of the black hole candidate X-ray binary XTE J1752-223 (discovered by RXTE; ATel #2258) with the 2-m Faulkes Telescopes North and South (located at Haleakala on Maui and Siding Spring, Australia, respectively). Exposures in B, V, R and i'-bands (mostly 100-sec exposures each) were taken every ~ 3 days since 2010-03-22 (MJD 55277). The optical counterpart (ATels #2263, #2268, #2424) is detected up until 2010-07-15 (MJD 55392), after which detections become ambiguous due to close field stars in this crowded region of the Galactic plane.
