The new big 22-m radio-telescope of Crimean Observatory shown on Figure 1 appeared to be of very good quality: for radio emission at λ = 8 mm the antenna beam is 1′.6, the efficiency ≅0·4, and the error of automatic pointing (guiding) does not exceed ±20″. A Dicke type radiometer was used as receiver possessing a sensitivity ≃2°K at the time constant τ = 1 sec, and pass-band ~30 MHz. The error in the contrast determination does not exceed ±0·5% of the level nearly corresponding to that of the quiet Sun. The scanning of the solar image is made in right ascension with velocity 0·5 sec in sec of time, the distance between successive scans in δ being 1′.5. An example of a single scan is shown in Figure 2, where the scan through Jupiter (for the determination of antenna beam) is also presented (for description see Moiseev, 1968).
