Wikipedia's LCROSS says:
Centaur impacted successfully on October 9, 2009, at 11:31 UTC. The Shepherding Spacecraft descended through Centaur's ejectate plume, collected and relayed data, impacting six minutes later at 11:37 UTC.
Contrary to media reports at the time, neither the impact nor its dust cloud could be seen from Earth, using the naked eye or telescopes.
But what about the SpaceX cis-lunar 2nd stage from the 2015 DSCOVR launch Chang'e 5-T1 mission rocket part? It's supposed to hit the Moon on March 4th.
Question: Where will Elon's that rocket hit the Moon? Will it be visible from Earth?

- BBC: "In 2009 Prof McDowell & other astronomers performed an experiment in which a similar-sized rocket was crashed into the Moon." Really? Which one?
- BBC: "A rocket launched by Elon Musk's space exploration company is on course to crash into the Moon and explode." Will it really explode?
