The Toruń Centre for Astronomy is an optical and radio observatory located at near about 15 km north of Toruń, Poland. It houses two single-dish antenna telescopes, 32 metres and 15 metres in diameter, as well as the largest Polish optical telescope - 90-cm Schmidt-Cassegrain camera. The facility is operated by the Nicolaus Copernicus University. Also, photometry using 60-cm Cassegrain telescope is made and radio measurements of the Sun at 127MHz frequency are recorded on a daily basis since 1958 using 23m interferometer.
Since 1981 the observatory has been a part of world wide network of radio telescopes participating in VLBI (Very Long Baseline Interferometry). The 32 m telescope is a 620-ton construction designed by Zygmunt Bujakowski. It is used in VLBI experiments, as well as spectroscopic, flux, polarisation measurements and pulsar observations. Currently receivers for frequencies 1.4-1.8GHz, 5GHz, 6.5GHz, 10.8GHz and 30GHz are in use.
