Mass transport above sunspots

Nils Brynildsen; O. Kjeldseth-Moe; Guenter E. Brueckner

Mass transport in the transition zone above a sunspot has been studied in theCiv line at 1548 Å, formed at 100 000 K. Four spectral rasters have been used, each covering 60×50 are sec. These have been observed with the High Resolution Telescope and Spectrograph during the Spacelab-2 mission in 1985.Flow velocities are derived from multiple Gaussian components fitted to the observed line intensity profiles. Density sensitive lines were used to find a relation between theCiv line intensity and the particle density. This relation is used in the mass flux calculations. The investigation indicates a clear net downward mass flux above sunspots.
