We Come In Peace

Last night Robyn spotted something that looked like this out our front window, which faces west. I thought it might have been a partially illuminated cloud since it was about thirty minutes after sunset. As we were standing in the street staring at it for about ten minutes, some neighbors drove by and said they thought it might have been an aircraft from Luke AFB. Turns out it was not:
a. the end of the world
b. an alien invasion
c. a cloud
It was actually this. The rocket was launched from Vandenberg AFB near Santa Barbara. Very impressive. The conditions were nearly perfect for viewing this dramatic sight all over the western US.
