In regards to the NSO observatory shutdown in New Mexico. Issues with web archive relating specifically to the Sep 3, 2018 snapshot.
4 X class flares
Also, for all that is holy, do not go down the rabbithole and search for Anna L.h.hughes NSO images on DDG. Not enough eyebleach in the world. (Was trying to find out what happened to the researchers there on twitter etc. I was not prepared for the horror.)
Also, this is directly between White Sands Missile range and AFB - and roswell, on the mountain range between. Just found it interesting.
Also, it wasnt the Observatory that was the only thing shutdown. The Sunspot Post office was also shutdown. If this was to prevent people from seeing something in the last few weeks to the next several months, its a rather ineffective means of doing so. Maybe some sort of biological attack was mailed there? Or was something shipped from there? Speculation will run rampant until more details emerge.
