Abstract	The visible and near-infrared imaging spectrometer on board the Yutu-2 rover of Chang'E-4 mission has conducted 2 sets of spectrophotometric measurements at two sites on its 10(th) lunar day. At each site, the reflectance spectra were measured on the same lunar regolith at different geometric configurations. The experiments reveal an increasing trend of the spectral reddening effect with the increasing phase angles, which may cause significant uncertainties on interpreting the maturity of the lunar regolith. Furthermore, the phase angles have significant effects on the 2-mu m band center and the 1-mu m band depth of the spectra, consequently on the estimation of mineral composition of the regolith. Finally, the derived average Hapke parameters using the in situ spectrophotometric measurements provide important ground-truth for remote sensing observations.
