AstroSat Soft X-ray Telescope (SXT) views the blazar PKS2155-304

The Soft X-ray Telescope (SXT) camera door was opened on 26 October, 2015. The first object viewed was a blazar PKS2155-304. Blazars are a particular type of quasars which are also high energy gamma
ray sources.
The observations from the telescope are fine and SXT instrument calibrations are underway.
