Ankara University Observatory


The Ankara University Observatory , is a ground-based astronomical observatory operated by the Astronomy and Space Sciences Department at Ankara University's Faculty of Science. Established in 1959 by Dutch astronomer Egbert Adriaan Kreiken in Ahlatlıbel, Ankara. Currently, it consists of nine optical telescopes and a radio telescope, which is currently taken out of service. Old instruments are displayed in a museum at the observatory.

History

Ankara University's Faculty of Science decided in 1954 to establish an observatory to begin with astronomical studies. Ahlatlıbel in Gölbaşı, Ankara was chosen as the ideal site, a location with dark skies far from the city's downtown to avoid the effects of light pollution, having an average 300 clear nights per year and also offering easy transportation from the campus. It is situated south of Ankara at an altitude of.
Groundbreaking of the main building and the three domes took place in 1959. The observatory was officially inaugurated on August 26, 1963, accompanied by an international astronomy conference. The scientific studies were carried out in the beginning with a radio telescope produced by the Dutch PTT, a 5 cm astrograph, a 15 cm Coudé telescope of Zeiss from Germany for solar observations, a Hilger and Watts microphotometer and a Cuffey Iris photometer.

Meteorological station

There is a meteorological station for observing atmospheric conditions such as temperature, humidity, barometric pressure, wind speed and wind direction as well as precipitation amounts. The gathered data is published also on the internet every five minutes.
