Beam me up, Scotty...

It's sunrise and I see a big blue streak coming straight down (or up). What in the world? I've seen bands radiating out from the sun but never one going perpendicular to the ground, or the sea, as was the case here. Still haven't figured out what caused this, and it was not something in the camera. All I can come up with is that maybe this is my portal to a giant spaceship... right Scotty? It made for some interesting speculation but no real answer yet.
