โœฆ Synopsis

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 des day -1. Our results are in agreement with those of Howard and Harvey from 1966-68. We intend to use this technique in a long-term program at Oberlin to monitor the equatorial rotation rate.

We have used an atomic-beam resonance-scattering technique applied to the 7699,~ solar potassium absorption line to make an absolute spectroscopic determination of the solar equatorial rotation rate. To our knowledge this is a new method which has not previously been used for studying solar rotation
