It’s so big we can see it with a telescope, and so small that the chance of something similar hitting any single spot on the surface minuscule in the next 100 years.
Basically, moon bases need to be underground to prevent micrometeoroids from messing them up, and any bigger impact like this is going to wipe out anything we build, even underground.
All the more reason Earth is pretty awesome!
Fun fact: moon regolith is made of ~45% oxygen, so in a roundabout way digging underground is kind of like having an atmosphere.
In some more enlightened timeline there's a spirited competition between institutional and amateur astronomers towards predicting these, and some amateur is sitting on a $10M this-person-told-us-so-and-we-bet-against-them prize, which gets bigger every year (no prizes for the institutional side, they get a salary).
In that timeline's future we're then competing over who can most reliably prevent them.
The winners of such frivolous competitions over protecting the moon get funding for the more serious job of protecting Earth.
I don't even get that far but get a blank page except for: "Please enable JS and disable any ad blocker." They're doing a pretty good job of minimizing their traffic.
For the rest of the world, this is ~222 meters, more than twice the length of a 100 meter track.

FFS, just use metric! Apparently that's about 1.7m.
