Recent observations of solar oscillations at SCLERA
This work deals with the subject of global solar oscillations. These oscillations are observed as fluctuations in the diameter of the sun. A diameter is determined by a mathematical solar edge definition at the SCLERA1 instrument. The oscillations have periods ranging from a few minutes to several hours and have amplitudes measured in millionths of a solar radius. These small amplitudes are observable only due to the unique properties of the edge definition. The properties of the observed solar oscillations are determined from the data; their statistical significance and repeatability are then tested.
