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