With completion of adjustments of the N-S line in 1985, SSRT initiated an all-weather monitoring of solar activity in the one-dimensional mode with an angular resolution as high as 15" using both linear interferometers. The team of authors was awarded the Prize of the Russian Federation Government in the field of science and technology for the year 1996. | ||

Two-dimensional mapping is done concurrently with one-dimensional images obtained in the additive mode. The correlation mode with high sensitivity permits low-constrast features on the Sun to be investigated. The additive-correlation mode ensures, at a sacrifice in sensitivity, a simultaneous construction of radio maps with a fast recording in the one-dimensional mode at the time resolution of 56 ms, which is important in observations of active processes when a reduction in sensitivity is not critical and the active region image can be obtained every minute. | ||

The Radio-Astrophysical Observatory (RAO) is in the Tunka Valley that separates two ranges of the East Sayan, 220 km from Irkutsk (51°45′33″ N, 102°13′08″ E). The Observatory site survey (https://goo.gl/maps/895pyjucMxabSPKw9) was determined by minimizing technogenous noise. At the moment, the main instruments are a radioheliograph and a suite of integral flux spectro-polarimeters. The RAO staff equals about 40, the operation time being 00–10 UT.
