Explanation: No, the car was not in danger of being vacuumed into space by the big sky vortex. For one reason, the vortex was really an aurora, and since auroras are created by particles striking the Earth from space, they do not create a vacuum. This rapidly developing auroral display was caused by a Coronal Mass Ejection from the Sun that passed by the Earth closely enough to cause a ripple in Earth's magnetosphere. The upper red parts of the aurora occur over 250 kilometers high with its red glow created by atmospheric atomic oxygen directly energized by incoming particles. The lower green parts of the aurora occur over 100 kilometers high with its green glow created by atmospheric atomic oxygen energized indirectly by collisions with first-energized molecular nitrogen. Below 100 kilometers, there is little atomic oxygen, which is why auroras end abruptly. The concentric cylinders depict a dramatic auroral corona as seen from the side. The featured image was created from a single 3-second exposure taken in mid-March over Lake Myvatn in Iceland.

All you need with that is some Pink Floyd.

I’m in the middle of a campaign in “The Long Dark” and alt-tabbed over to check the news and bang, and Aurora.
COOL!

I saw Pink Floyd twice, both times at Tampa Stadium (what ever the stadium name was/is). The laser shows were incredible.

"All you need with that is some Pink Floyd." All you need with almost anything is some Pink Floyd.
Wrong! Do it again...
Time to go...
