Also, photometry using 60 cm Cassegrain telescope is made and radio measurements of the Sun at 127 MHz frequency have been recorded on a daily basis since 1958 using a 23 m interferometer.
Since 1981 the observatory has been a part of worldwide network of radio telescopes participating in VLBI (Very Long Baseline Interferometry).
The 32 m telescope is a 620-ton construction designed by Zygmunt Bujakowski based on initial geometric parameters created by Dr Jerzy Usowicz.
In addition, the development of instrumentation for radio astronomy (ultra low noise receivers, spectrometers, frequency converters, digital electronics, control systems) is also a significant part of activities in the observatory.
From 1998, the department undertook the additional function of a National Facility with a major aims of serving Polish astronomers and emphasizing international cooperation.
