The solar active regions observations were carried out with facilities for multi-spectral investigations of solar atmosphere on Large solar coronagraph of Sayan observatory. The facilities permits to perform the spectral observations in selected chromospheric and coronal lines simultaneously with obtaining of $H_\alpha$ and He I images.

In this work we analyze the results of spectral observations in the range from 10824 Å to 10835 Å (the He I 10830 Å and Si I 10827 Å lines) and images of the sunspot umbrae in the He I 10830 Å.To search for other articles by the author(s) go to: http://adsabs.harvard.edu/abstract_service.html
