One Year of ASTROSAT
On Sept 28, 2016 AstroSat completed one year in orbit. In this time, the spacecraft orbited the earth more than 5400 times and executed 343 individual pointings to 141 different cosmic sources. The observed data are being routinely downloaded at the Indian Space Science Data Centre (ISSDC) at every visible pass and are being processed at the Payload Operation Centres. The archive and dissemination system at the ISSDC will soon be operational to serve this data to the world community. October 1, 2016 will mark the beginning of the open phase of the observatory. Available observing time over the subsequent six-month period (Cycle A02: October 2016-March 2017) was oversubscribed by a factor of six in observing proposals received from researchers in 59 different institutions. The rigorous process of selection of proposals and their scheduling has been completed, and AstroSat is now ready to embark on the open phase observations.
In order to mark the completion of one year of the observatory a one day science meeting was held at IUCAA on 29 September 2016. During this meeting the ASTROSAT Science Support Cell (ASSC) was formally dedicated to the nation by the chairman, ISRO
