Visitors Guide to the Narrabri Observatory


The Narrabri Observatory is part of the Australia Telescope National Facility (ATNF), which is operated by the CSIRO. The site contains the Australia Telescope Compact Array (ATCA), which consists of five moveable antennas on a 3-km east-west railtrack with a 200m north-south spur, and a 6th antenna 3 km further to the west. The site used to be the home of the CSIRO's solar radioheliograph. The central area of the observatory contains a control building with offices, a library, laboratories, workshops, and The Lodge for visitors and local staff.

Also on site are the Sydney University Stellar Interferometer (SUSI), Bureau of Meteorology - Space Weather Services and the University of Birmingham solar seismology installation.

The Observatory is situated 24 km west of the town of Narrabri, which is approximately 540 km north-west of Sydney. Narrabri has a population of about 7,250 and is the centre of a large irrigation and dry-land farming district which produces cotton, oilseed, premium grade wheat, grain sorghum, and raises cattle and sheep. Some of the surrounding tourist attractions are described at the end of this guide.

The telescope is at latitude -30.31498, longitude +149.56394 (east of Greenwich) and is 240m above sea level. The environment is modestly dry. Temperatures are typically above 30oC on summer afternoons (e.g. January,February), and are close to 0oC on winter mornings (e.g. June, July).
