Probably a launch from Vandenburg AFB. That’s what they look like.
I am on the list of the Vandenburg launches and there were no scheduled launches on that date. The military (Navy) sometimes launches rockets without announcement. Perhaps it could have been a military launch?
LA’S DELTA IV HEAVY
What is it launching? The military’s primary launch provider, the United Launch Alliance, is planning to launch its most powerful vehicle, the Delta IV Heavy. On the rocket is a classified satellite for the National Reconnaissance Office called NROL-71. Since it’s classified we don’t know much about it, though we do have one of the NRO’s intense mission patches — which sports an angry-looking eagle.
It looks like a crashing UFO.
