| Popis: | On the occasion of the 175-year anniversary of the Moscow State University Sternberg Astronomical Institute we would like to outline the history and some results obtained by the Institute in cooperation with the Ondřejov Astronomical Institute of the Czech Republic Academy of Sciences. The development and current state of this cooperation and the mutual solar observation results are presented. At the end of the 20th century, by a special international contract between the two institutes, one of the five Carl Zeiss new solar instruments, namely the ‘Horizontal Sonnen Forschungs Anlage’ (HSFA) was installed at the High-altitude Sternberg Institute Observatory near Alma-Ata. In the 1980s four other instruments were mounted in Czechoslovakia (two of them in Ondřejov and the other two in Stara Lesna and Hurbanovo). Both Ondřejov instruments (HSFA 1 and 2) were modernized over the period in the 2000–2004, mainly to improve their electronic control systems. A new spectral grating, corresponding optics and detect... |
