- Аннотация: One of the principal problems of investigation of AGNs is to understand the nature of the central objects and the physical processes which yield their gigantic luminosities. This requires us to consider the innermost parts of AGNs. 1 - 3$^d$ variations of the relative shape of broad emission line profiles of active galactic nuclei are perhaps the most informative probe of their innermost parts (r = 10$^15-16$cm from the centre). Optimal objects for these obervations are Sy 1.5 with strong variations of the non-thermal continuum. The expected amplitude of the variations ranges from a few percent to 10 - 20 %. The optimal spectral resolution is 0.5 - 5 Å. It is very desirable to complement spectral observations with photometric data. The results of the first set of such observations with the 6-meter telescope are reported.
