Paper Abstract

A soft X-ray focusing Telescope (SXT) was launched in a near Earth, near equatorial orbit aboard the AstroSat on September 28th, 2015. The SXT electronics was switched on within 3 days of the launch and the first light was seen on October 26th, 2015 after a sequence of operations involving venting of the camera, cooling of the CCD, opening of the telescope door followed by the opening of the camera door. Several cosmic X-ray sources have been observed since then during the Performance Verification phase. A few near-simultaneous observations have also been carried out with the Swift observatory. The in-orbit performance of the SXT based on these observations is presented here.
