For both periods of the double-mode classical Cepheid AS Cas we have constructed $$O-C$$ diagrams spanning a time interval of 132 years. The $$O-C$$ diagrams have the shape of parabolas, which has allowed us for the first time to determine the quadra

For two classical Cepheids, CEa Cas and CEb Cas, members of the open cluster NGC 7790, we have constructed $$O-C$$ diagrams spanning a time interval of 125 years. The $$O-C$$ diagrams have the shape of parabolas, which has allowed us for the first ti

$$BVI_{c}g^{\prime}r^{\prime}i^{\prime}$$ observations of the classical Cepheid V1467 Cyg have been obtained with the 60-cm telescope at the Caucasus Mountain Observatory of the SAI MSU. Invoking all of the available photometry has allowed an $$O-C$$

We present the results of photometric and spectroscopic monitoring campaigns of the changing look AGN NGC 3516 carried out in 2018 to 2020 covering the wavelength range from the X-ray to the optical. The facilities included the telescopes of the CMO

We present observations from the short-term intensive optical campaign (from Sep2019 to Jan2020) of the changing-look Seyfert NGC 3516. This active galactic nucleus is known to have strong optical variability and has changed its type in the past. It
