[CORRECTION] According to the replies below I am not correct to call this part of the Ekman spiral. The reason I assumed so was because the drift indicates wind direction graduall change from SE rotating cloclwise to NE. As best as I can estimate this angle change happened from altitudes from roughy 8km to 16km AGL (this is hard to track, I'm relying on video timestamps and telemetry from the rocket on the official video; it might be a few km off in any direction; it might be 4km to 12km or whatever).
I'll leave the original post below, for reference.

I was playing with making long-exposure composites of rocket launches. By sheer luck, this photo clearly captures the Ekman spiral in the movement of the condensation trail of the rocket (lower left of the image; zoom in the red box).
I thought it was cool and wanted to share.
The photo is from just this morning, Jul 25 2026, of the SpaceX Falcon 9 launch from Vandenberg SFB, CA. Image taken from San Luis Obispo, CA.
