AstroSat Updates As on 19/10/2015
The first Astroronomer's telegram (Atel no. 8185) on SSM observations of GRS 1915+105 released on 18 October 2015. The Scanning sky Monitor (SSM) was pointed to GRS 1915+105 and caught it exhibiting the 'beta' class of variability on 14 October 2015. This is one of the many types of variability this source exhibits some of which are associated with its spectral states also. The Soft X-ray Telescope (SXT) door was opened successfully on October 15, 2015. It will observe the sky however after the camera door is made open which will be after about 10 days. The High voltage of Near UV, Visible channel and Far UV channel of the UV Imaging telescope (UVIT) was switched ON and detectors tested with low gain and found satisfactory and put back in OFF condition (16 and 17 Oct. 2015).
