Report

Photometric observations of the mutual phenomena of the Galilean satellites at the Pulkovo observatory in 2014-2015

Autor: Khovritchev, M. Yu., Izmailov, I. S., Roshchina, E. A., Gorshanov, D. L., Kulikova, A. M.

We present the results of photometric observations of the mutual phenomena in the system of Galilean satellites obtained during 2014-2015. The observations were performed using the 26-inch refractor, Normal Astrograph, ZA-320 telescope of the Pulkovo

Report

Astrometric observations of outer Jovian satellites with the `Saturn' telescope. First results

Autor: Khovritchev, M. Yu., Ershova, A. P., Balyaev, I. A., Bikulova, D. A., Izmailov, I. S., Roshchina, E. A., Petjur, V. V., Shumilov, A. A., Maksimova, L. A., Oskina, K. I., Apetyan, A. A., Kulikova, A. M.

The one-meter telescope-reflector `Saturn' (D=1 m, F = 4 m) was partially renovated at the Pulkovo observatory at the end of 2014. The telescope was equipped by CCD camera S2C with 14x14 arcmin field of view and 824 mas per pix scale. The observation
