Timau National Observatory

On a hillside plateau in Kupang Regency, East Nusa Tenggara, the Timau National Observatory is Indonesia's newest astronomical site, and is set to become the largest in Southeast Asia.

About Timau National Observatory

The observatory occupies roughly 34-35 hectares of hilly land at the foot of Mount Timau in the Central Amfoang District, about 130 kilometres northeast of Kupang city. It is operated by Indonesia's National Research and Innovation Agency (BRIN).

History

Construction began in 2021, with completion targeted for 2025, positioning Timau as Indonesia's newest observatory and the largest facility of its kind in Southeast Asia.

Telescopes & research

Its centrepiece is a 3.8-metre telescope weighing around 20 tons, the largest planned for the region, supplemented by a 1.2-metre telescope, twin 50 cm observation telescopes, and a 30 cm solar telescope. The site will support scientific research alongside education and public outreach in astronomy and space science.

Location & getting there

At 1,347 metres above sea level, the site was chosen for its low light pollution, relatively easy access, and East Nusa Tenggara's notably clear skies, with cloud-free conditions recorded above 65% of the year.
