Areas of sunspots and their positions taken from the Greenwich Photoheliographic Results (1874-1976) and typical intensities of the umbrae and penumbrae are used to calculate daily values of the solar flux at a wavelength of about 500 nm. Using overlapping time series of 512 days each solar rotation

Photospheric and chromospheric spectroscopic Doppler rotation rates for the full solar disk are analyzed for the period July, 1966 to July, 1978. An approximately linear secular increase of the equatorial rate of 3.7% for these 12 years is found (in confirmation of Howard, 1976). The high latitude r
We have made absolute measurements at Kitt Peak of the dependence of solar rotation rate upon latitude during the period 17-20 June 1977. We observed the solar potassium line at 7699,1k using an atomic-beam resonance scattering apparatus. The measured sidereal equatorial rotation rate is 13.5 + 0.5
