The solar synoptic telescope SOLSYT for studying solar magnetism and space weather
In the physics of the Sun growing attention is paid to regular long-term measurements of magnetic fields covering the whole solar surface. Only having such information, it is possible (under certain assumptions) to calculate parameters of the heliosphere and predict geoeffective phenomena. Therefore, considerable world-wide attention is given to the construction of instruments capable to provide such observations. To create in Russia a modern telescope capable of performing the full-disk and full-vector measurements with high spatial and temporal resolution, a few years ago at ISTP SB RAS, in cooperation with LOMO JSC, there were started works on the development and creation of a new solar instrument, which, based on its main scientific goals, was named the Solar Synoptic Telescope SOLSYT. In June 2017, SOLSYT was installed in a specially constructed tower at the Baikal Astrophysical Observatory, and necessary actions were initiated to organize regular observations with it. The paper provides basic information about the optical scheme and the structural elements of SOLSYT.
