Telescope
RATAN-600 is a radio telescope with a variable-profile circular antenna of 600 m in diameter, the largest Russian telescope, which performs mass measurements of galactic and extragalactic radio sources at frequencies of 1.2, 2.3, 4.7, 8.2, 11.2, and 22.3 GHz quasi-simultaneously (within 1-3 min). The main advantages of the instrument are high brightness-temperature sensitivity and multifrequency observations.

Daily Sun observations
The figure shows multiwave radio emission scans - graphs of the distribution of intensity I and circular polarization V across the solar disk, obtained with RATAN-600. The color scale on the right corresponds to 80 wavelengths in the range from 1.65 cm to 10 cm. The upper left hand corner shows the date and time of obtaining the radio data (available on the page with a detailed information). Polarized emission V characterizes the magnetic-field strength in solar active regions.
