Did anyone else notice the FAA flight restriction zones that quietly appeared over rural Nevada last month?

Noticed this about three weeks ago actually, was cross-referencing some NOTAM data against historical satellite imagery of that region for something completely unrelated and the new restricted zones jumped out immediately. What's interesting isn't just that they appeared but how they're positioned - they don't align with any known test range boundaries or established military corridors. That kind of irregular geometry usually means something operational rather than administrative.

The FAA classifies these under different pretexts depending on whats underneath them, so the listed reason often tells you nothing useful. What I'd be looking at is the altitude ceiling on each zone and whether there are any associated ground-based radar signatures showing up in amateur receiver data from the area.

Has anyone managed to pull the actual NOTAM identifiers? If we can date exactly when each one was filed that might correlate with other activity people have spotted. There were some unusual atmospheric observations reported out of that region around the same period that I want to map against this properly.

Completely normal, nothing to see here, just the government quietly cordoning off another chunk of desert for "weather monitoring" or whatever they're calling it this week.

Jokes aside though, the NOTAM angle is actually the most solid way to track this stuff - FAA data doesn't lie and it's publicly accessible which is probably more than they bargained for when they set these
