i've seen a vid on YT thats states that they closed the observatory because they found out that the Chinese are spying the Holloman Airbase wich is near by. Even a german Newspaper states that the Chinese caught spying there.

Thats a fucking cover up story.
Even if they would have caught the chinese spying. Is that a reason to close other observatories and livestreams from the sun?
