It's doubtful that much will be seen with amateur telescopes....The moon is pretty low in the south at the impact event time (for northern hemisphere/western US observers). The conservative predictions suggest that IF the impact kicks up a dust plume, and IF the dust rises high enough from the lunar surface to be illuminated by sunlight, then something MIGHT be visible. The spacecraft is pretty small, and the predicted impact crater will be only a few hundred feet in diameter, not big enough to be visible directly in amateur telescopes. The event favors observations with LARGE telescopes in the southern hemisphere, esp. at Infrared (IR) wavelengths.
