Abstract
Astronomy has always been at the forefront of information technology, moving from the era of photographic plates, to digital snapshots and now to digital movies of the sky. This has brought about a data explosion with multi- terabyte surveys already happening and upcoming petabyte scale surveys. By scanning the sky repeatedly and automatically, astronomers find rapidly changing phenomena - transients - of a great variety. Surveys like the Catalina Real-time Transient Survey (CRTS) publish details on the transients right away since many of these fade in a matter of minutes and it is important to get additional observations in order to determine their nature. This involves being able to combine a variety of datasets, small and large, in real-time. With networks like the Asia Pacific Advanced Network (APAN) and India's National Knowledge Network (NKN) we are in the realm where such a data…
