Sunspot velocity fields
- Abstract:
-
Research in sunspot velocity fields was initiated by Evershed in 1909. He observed that, in general, Fraunhofer lines crossing a sunspot appeared to be equally displaced in wavelength in opposite directions on either aide of the spot, and subsequent measures of sunspot spectra enabled him to deduce a radial outflow from the spot centre over the surface of the sun, the maximum value of which approached 2 Km/sec, This sunspot feature has since been referred to as the Evershed effect. In addi...
