On Lunar Opposition Spike Observed by Clementine
Abstract
A novel way of extracting the phase curves from the Clementine UVVIS images is presented. The method is based on subtraction of two images taken consequently in different filters. Due to spacecraft motion the zero phase angle point moved on the surface. After the subtraction the albedo pattern is practically quenched, but the opposition spot is not quenched completely due to the shift of the phase angle pattern. Typical values of the opposition spike amplitude measured with the present method in phase angle range of 0.2 to 1.6 deg agrees with measurements in Buratti et al. (1996) made with the method of global averaging.
