When a SpaceX Falcon launches an hour or so before sunrise the exhaust in the upper atmosphere is visible as the earth rotates under the stratosphere. When the sun revels itself from the shadow of the earth it illuminates the stratospheric level cloud of dust as it tracks back west to the Cape.
These are called Nocturnal Clouds which are usually caused by meteor dust when entering the upper atmosphere just before dawn. We get man made Nocturnal Clouds here if the timing is right.
The first Time Lapse video launch was at 5:02, by 5:30 you start to see the cloud appear as the sun shines in the upper atmosphere. This one is special wait for the rotating square cloud near the end.

I've been doing time lapse since I got my first 16mm camera in the early 70's. You would shoot a job for a client and have film left over. No good cameraman would not use up the rest of the film roll for aa fun project before processing and client is paying . You get a freebee film for you too too.
