Kušnirák at Ondřejov. Vojtech Rušin (b. 1942), solar physicist of the Astronomical Institute, Slovak Academy of Sciences, is well known for his contribution to dynamics of prominences and corona. He was one of the first observers at the Lomnický Peak coronal station and greatly engaged in its further development.
