Massive Explosion This Week at White Sands

I pointed out to John this remarkable Socorro County 'Weather' on a clear and calm night:

John at first noted:

Hmm. It appears to be well north of US Hwy 380 which would put it outside of the WSMR boundaries, although I recall that the area directly to the north was a region they sometimes closed off for tests. Chaff testing seems unlikely since it's old technology and, one would presume, there is not a whole lot more that could be done with it. Maybe it's a malevolent spirit rising up from the old pueblo ruin you saw there...

Later, he reported:

Here is a video loop of the still radar picture you sent yesterday. There were plenty of large explosions at White Sands when we were there but I've never before seen anything like this reported.
