• Ankara University Kreiken Observatory was founded by Prof. Dr. E. A. Kreiken in 1954. Ahlatlıbel district, 18 km south of Ankara, an easy-to-reach area and away from city lights, was chosen to be the location of the observatory due to the fact that the sky has been suitable for observation about 300 days of the year. Recently, there has been six telescopes at the facility to use for scientific and popular purposes. For the scientific studies, 35 cm diameter T35 telescope with a high-tech CCD camera and 40 cm diameter T40 Kreiken telescope with a medium resolution echelle spectrograph are used. On the other hand, 15 cm diameter Coude telescope, 20 cm diameter Meade LX200 ACF telescope, 12.5 cm diameter Meade ETX-125 telescope and SolarMax II Solar Telescope are also in use for the popular events.

    Scientific studies in the observatory are carried out in two ways; photometric and spectroscopic observations. While photometric observations mainly focuses on binary stars, variable stars and exo-planets, spectroscopic studies are mostly related to active stars, Doppler imaging, chemical abundance analysis, and radial velocity measurements.

    Additionally, public and special astronomy events are monthly held in the observatory. In the public events, various presentations related to interesting astronomy subjects are given and the objects (Venus, Jupiter, Moon, etc.) in the sky that night are observed. In the special events, it is possible to observe natural events such as lunar eclipses and meteor showers in the facility.
