Der Flug von Spektro-Stratoskop.
Abstract
The paper gives a general description of the Spektro-Stratoskop, a balloon-borne solar spectrometer which in May 1975 successfully performed a series of observations from the stratosphere on the evolution of solar granulation, bringing back to earth time-lapse photographs of granulation on various parts of the solar disk. At present, some qualitative results have been obtained from the data. It has been determined that neither wave phenomena nor stationary convection cells are involved in granulation. Most of the granulation elements develop in an 'explosive-like' manner: an at first rather insignificant small granule becomes brighter, expands (occasionally in the shape of a ring), and finally breaks up into smaller fragments, which either disappear or repeat the process, which lasts from 10 to 20 minutes.
