| Abstract: | From the results of photometric and polarimetric observations in three colors of small areas of the Moon's illuminated surface, taking stars as the photometric standards, it is concluded that the Moon's surface brightness often fluctuates from the luminosity calculated by Hapke's formula. It seems that the Moon's light is composed of a part which is completely ruled by Hapke's law and has a uniform polarization degree over the entire illuminated surface, and a part which is quite nonpolarized. The brightness fluctuation is due to the variation of the latter part. The enhancement of the brightness is more remarkable in red color than in yellow and blue colors. |
