With FBI involved and it being a scientific location without money ties, it can only be terrorism or national security.
In case of nat. sec., it could be that they discovered something alarming?
Does anyone have solar images from ~1 week onwards before and on Sept 6th? There are none in the forum section.
Spaceweather's archive from Sept 6 and 7 shows a sun image with a growing big coronal hole, on
Sept 8 meandering from the southern end almost to the north pole. Impressive. Beautiful, too.
But ... is that something so disturbing that a telescope gets evacuated and closed off by FBI to stop news from spreading?
What can you imagine in your most daring phantasies as reason of national security or terrorism to evacuate and close a solar telescope?
