21-27 Dec. 1968) --- View of the lunar surface as photographed from the Apollo 8 spacecraft. Zero-phase bright spot. With near-vertical sun illumination, topographical detail is washed out and differences in surface brightness are accentuated. The numerous small bright-halo craters become conspicuous. A few larger craters have extremely bright inner walls that are commonly streaked by darker material. The bright glow near the conspicuous bright-walled crater is a halo that surrounds the position of the spacecraft shadow.
