Not sure what the collective term for cosmic rays is (a 'kaleidoscope' sounds good) ~ this looks like a whole bunch of them

Never seen that many cosmic rays before.
Perhaps some energetic outburst?

That’s cool! See how they are all in a narrow vertical strip? That’s because we only have one z-band exposure in that strip, so the outlier-rejection isn’t able to flag them! And that happened to coincide with this strong CR shower.
