No idea what sort of launch this is
Oh wow, that’s really cool!
Thanks! So it turns out this was the SpaceX Falcon 9 rocket launch from Vandenberg.
The bright spot at the left moved across the sky, trailing a shell of vapor.
I ran back inside shouting “come see this, fast!” and grabbed the better camera, but it wouldn’t focus, so I snapped this with my phone.
The vapor trail persisted for another 10 minutes after the rocket and booster stage (I could briefly see an expanding ring around the booster) were no longer visible, and it was high enough to continue reflecting sunlight even though it was long after sunset.On Tumblr
