GRB. Just have to be in the path, and the Ordovician extinction, which is very different from the other big 5 bears a lot of the signs it happened almost half a billion years ago.

What are the frequencies of these occurring?

Several times a day, but I should clarify that you would still need to be fairly close, say 50-100 light years away, and then also be directly in the path. I think Eta is the closest binary capable of producing GRB and it’s 7500 light years or more and offset 45 degrees so we wouldn’t be in the path anyways. Universe is a big place.

EDIT: I only have the most rudimentary of knowledge in this area, and even that’s a stretch. I would verify.
