我们报告了使用 RATAN-600 射电望远镜对 NOAA 10848 活动区域进行光谱偏振观测的结果。高光谱分辨率 (1%) 的观测允许获得位于从色球层到日冕过渡区域的太阳黑子上方的光源的详细温度高度剖面。由此产生的垂直剖面表明，太阳黑子上方的过渡区域可能会延伸相当大的高度间隔，并以温度逐渐升高为特征，这种模式与过渡区域温度急剧升高的模型大气不一致。
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.
