Selangor Observatory

Selangor Observatory is an astronomy centre in Sungai Lang, Sabak Bernam, Selangor, Malaysia, run by the Selangor State Mufti Department.

About Selangor Observatory

The observatory serves as a research and development centre for astronomy, with a role that blends scientific observation with Islamic calendar work: it carries out official crescent moon observations during Ramadan, Syawal, and Zulhijjah, along with routine monthly observations on the 29th of each month.

Telescopes & research

Beyond lunar sighting, the observatory tracks the moon, stars, planets, constellations, comets, and meteors to study changes in the celestial system, and it runs astronomy courses and seminars for the public. It collaborates with a range of institutions, including the Department of Survey and Mapping Malaysia (JUPEM), the Space Science Studies Division (BAKSA), the University of Malaya, the Department of Islamic Development Malaysia (JAKIM), and the International Islamic University College Selangor (KUIS).

Location & getting there

The observatory sits about 20 kilometres from Sabak Bernam town at an elevation of roughly 7 metres, facing the Straits of Malacca, in the Asia region of Malaysia.

Visiting Selangor Observatory

The observatory runs public courses and seminars alongside its research work; check with the Selangor State Mufti Department for current programme dates before planning a visit.
