Abstract (English):
The report presents the first results of test observations conducted since April 2024 on the RT-32 radio telescope of the ``Svetloe'' observatory at a wavelength of 3.5 cm. The observations were carried out in the quasi—circular scanning mode, a variant of scanning when the telescope sequentially tracks a number of points located on a circle. With the beam width of this instrument being 4 arcminutes, active regions and their sunspot components are easily identified in the entire limb zone, which is problematic, for example, for the RATAN-600 radio telescope. While not having high resolution, RT-32 successfully detects faint sources above the solar limb, which are poorly visible on the SRH radioheliograph. And the joint use of all three RT-32 radio telescopes makes it possible to monitor solar activity in the summer practically throughout the entire day.
