Two-color photoelectric photometry of the earthshine


  • F. A. Franklin


This paper presents two-color observations of the earthshine made during 14 nights of July and August 1965 at the Boyden Observatory in South Africa. Although the information provided is limited because the observations cover a range in phase angle of only 45°, it is possible to derive earth albedos of 0.30 in V and 0.36 in B, both accurate to about 10%.
