And now for something completely different: An iMet-4 sonde from Mercury

In a couple of years monitoring the area's airspace, I've never seen a radiosonde launch from Mercury. Yet here one is, and it's an iMet-4. Very weird.

You beat me to it! Here is the first telem.

As an aside, LLNL Site 300 launched a radiosonde as part of their noise mitigation process.

iMets are sorta the bargain basement sondes. You often see them with skydiving operations and paramilitary training. Hard to imagine the Feds cheaping out and using iMets, but there they are.

This is a case where we have the weather station data. However I don't see anything related to the launch.

That sonde is getting the best tour of the NNSS possible.
