Abstract
We report the results of RATAN-600 radio telescope observations of the fine structure of the source of cyclotron microwave emission (SCMR) located in the solar corona above the main sunspot of NOAA11899 active region. Compared to earlier and mostly episodic observations of the SCMR, our regular observations with RATAN-600 radio telescope showed rather conclusively that the variation of the structure of the SCMR as a function of the angle of view in the present case is of geometric nature. The behavior of image variations generally agree with the computations performed by Gelfreikh and Lubyshev in terms of the simplest model of the solar atmosphere above the sunspot. The results of their computations are widely used for interpreting observations.
