That last burstlet

4 hits over a threshold of 3 in one second. One of the 4 looks like a muon.

Unlike the last few, this one looks like a good background fluctuation rather
than a hot box. However, we're being bit by low statistics, without 1/3 the
detector. Which, BTW, goes back into action in an hour or so, as all the hot
boxes in uVAX#3 have been lut iterated back to sanity.
