Caution: This movie might not be suitable for people with epilepsy.

This movie shows the short-term dynamics Jupiter's southern storms derived from raw JunoCam images of Juno's Perijove-10 flyby on Dec 16, 2017.

You might also notice the effect of changing solar illumination on the appearence of the haze bands.

JunoCam usually takes a time-lapse sequence of images during each perijove showing Jupiter's polar regions.

These images are taken from different perspectives along Juno's trajectory.

But it's possible to reproject the JunoCam images to a common perspective. Displaying such a sequence rapidly reveals cloud motion in Jupiter's storm systems.

This movie applies this technique. At the same time, it is changing the simulated perspective along Juno's trajectory.

The same short sequence of images is displayed in a loop, but due to the changing way of reprojecting the raw images, the shown surface area is changing more or less continuously.

Jupiter is rotating. The animation follows Jupiter's rotation. Therefore, the line between day and night appears rotating.

The still imaages of the movie are partially illumination-adjusted, zoomed-in, and enhanced to the 4th power of radiometric values.
