The rotation of the sun - Observations at Stanford

摘要: Abstract : Measurements of the photospheric rotation rate using Doppler effect have been subject controversy since they were first made and recently reviewed. Daily observations at Stanford Solar Observatory 1976. Analysis 950 full-disk low-resolution dopplergrams to date yields results that conflict with some other recent sets observations. The SSO show no daily or long period variations in exceed observational error, average is about same as large-scale magnetic field structures sunspots. These conclusions are apparently inconsistent well-known Howard Harvey (1970). (Author)
