Pretty cool nFA.

Solarheads call that a lift-off. While it almost always is present, we can't always capture them because we are trying to shoot a "ball"... If the prom is not directly on the limb in our "flat" view, the "lift" is not really visible in our two-dimension view of the ball.

(I hope that made sense. LOL)

Perfectly good sense to me.
I hope that the cause of the fast oscillations during the lift was clear. The magnetic fields act directly on the charged particles. The charges then drag the neutral particles along through collisions. It's analogous to the squeak of chalk on a blackboard. (I date myself. ;) ) Lots of higher frequency stick-start.

We used to have some members who knew how to do time lapses of proms and stitch them together, haven't seen any lately though.
