What just happened there?

(There being, an hour or two ago)


Did anyone else notice outside darken just a little?
This is not the first time I recall momentary glitches in brightness from my eyes, but the first time in a long time I actually recognized what was happening; I can vaguely recall as a child maybe.. 6-9? Wondering if my eyes were malfunctioning because of the same thing. This time though, I think.. I wonder how big and fast, and how far away whatever just went past the sun was.
Or maybe a portal just opened.. I wonder what got through???;)
