Abstract • We present 5850 flux measurements of 58 extragalactic radio sources monitored at Metsahovi Radio Research Station and Crimean Astrophysical Observatory during the period 1985.5-1990.5. The Metsahovi observations are at 22, 37 and 87 GHz and the Crimean observations at 37 GHz. Together with the earlier 3000 measurements from 1980-1985 our data represent an order of magnitude increase in the number of available millimeter and near-mm continuum observations of active galactic nuclei. The calibration procedure of the observations is also described.
