Popis:	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 A to 10835 A (the He I 10830 A and Si I 10827 A lines) and images of the sunspot umbrae in the He I 10830 A.
