A group of amateur astronomers of Islamabad region gathered in November 2007 to work for the promotion of astronomy- related activities in an organized way. In its first meeting it was decided to name the group as Pakistan Astronomy Society (PAS) and later modified to PAS-Islamabad (PAS-ISB) to work as Islamabad chapter of PAS. It was hoped that other local, existing and future groups, may choose to become affiliates of Pakistan Astronomy Society.
The group retained the identity as Pakistan Astronomy Society-ISB for many years until recently where its name has been changed to Pak-Astronomers Islamabad (PAS-ISB). This change was brought about to avoid any ambiguity on the occasions of national and international representation.
