The Sky Watchers
Association, located in the city of Kolkata
(previously Calcutta) in India, is an
assemblage of persons interested in astronomy and sky watching. This
non-profit voluntary association welcomes
both the ordinary persons simply interested
to watch the splendour and beauty of the night sky and to adore its
endless variations, as well as more methodical and serious sky watchers who want to record their
observations on variable stars, solar events, occultations,
eclipses, comets, asteroids and so on. These data are collected and
analysed or forwarded to appropriate scientific bodies for analysis.
These observers thus can rightly claim to be indispensable, though
small, contributors to the advancement of human
knowledge base.
