Backyard Range-radio astronomy at Saint Mary´s University, Halifax, Canada

The Saint Mary´s University (SMU) radio observatory, located on the roof of the university´s McNally Administration Building, is described. The various antenna installations are used to conduct solar observations at the 21-, 7.5-, 5-, and 3-cm wavelengths. Facilities are also available for observations of the radio star Cassiopeia A. Two-element interferometer solar observations are routinely conducted by undergraduate physics students. Surprisingly good results for the angular extent of the Sun at the particular observing wavelength are obtained from these programs.<>
