Abstract
We report the results of spectral-polarization observations of the active region NOAA 10848 made with the RATAN-600 radio telescope. High spectral resolution (1%) of observations allowed obtaining detailed temperature height profiles for the sources located above the sunspots in the transition region from the chromosphere to the corona. The resulting vertical profiles indicate that the transition region above the sunspots may extend over a considerable height interval and be characterized by a gradual increase of temperature—a pattern that is inconsistent with model atmospheres having a sharp temperature increase in the transition region.
