Abstract The flight of the University of Birmingham X-ray Telescope, which took place between 29th July and 6 August 1985 is reviewed. Despite the competing demands of twelve other investigations on-board, it was found possible to plan an observing programme for the XRT which enabled a good (43%) utilisation of the total operating time to be achieved, and then to carry out this programme with high efficiency. An important element here was the inclusion within the XRT of a pointing mount, which enabled it to point with a degree of independence of the Orbiter vehicle. The background of spurious events in the detector, due mainly to energetic particles, was found to be low and well-behaved, except for occasional events which are not easy to distinguish from X-ray bursts. The spectral intensity of unrejected background varies from about 2.10−3/cm2sec keV at 8 keV to 5.10−4/cm2 sec keV at 25 keV.
