On July 11, 2017 (UTC), NASA's Juno probe successfully performed her Perijove-07 Jupiter flyby.

The movie covers 3 hours of this flyby in 125-fold time lapse, the time from 2017-07-11T00:45:00.000 to 2017-07-11T03:45:00.000.

It is based on 13 of the JunoCam images taken during the flyby, and on spacecraft trajectory data provided via SPICE kernel files.

For each of those 13 raw images, a short flyby scene has been rendered. Blending the scenes appropriately using the ffmpeg tool resulted in the movie.

During Perijove-07, the amount of storage available for JunoCam was restricted. Priority has been imaging of the Great Red Spot. Therefore, some large gaps in latitude coverage of good quality have been left open.

Most bright blips caused by energetic particle hits have been detected and filtered out by the rendering software.

This applies in a similar way to most of the more or less constant camera artifacts, too.

The still images are approximately illumination-adusted, i.e. almost flattened, and consecutively gamma-stretched to the 4th power of radiometric values, in order to enhance contrast and color.

Residual changes of brightness are due to imperfections of image processing.

Similar to previous perijove passes, the movie starts with views of Jupiter's northeren hemisphere, then approaches Jupiter's cloud tops up to about 3,500 km, before departure from Jupiter's southern hemisphere.

Closest approach was near 9.5 Jupiter-centric degrees northern latitude.

JunoCam was built and is operated by Malin Space Science Systems in San Diego / California / USA.

Many people at NASA, JPL, SwRI, and elsewhere have been, are, and will be required to plan and operate the Juno mission.
