Juno's perijove 5 is coming up less than two weeks from now - it's on March 27, 2017.
The target selection voting has started and is open until almost four days from now: https://www.missionjuno.swri.edu/junocam/voting?current A large part of the data volume will be reserved for polar time lapse sequences though. John Rogers has written a helpful summary of the upcoming perijove 5: https://www.britastro.org/node/9377 |

Youtube upload of Perijove-05 animation completed.
Youtube refused my AVI version; so I needed to upload a terribly large 500 MB+ MOV file. However, quality may have suffered a bit in the youtube version. The bluish-green can be of at least two reasons: - Jupiter's haze appears to be bluish, especially when seen from acute angles, and near the poles. - Some portions of some of the images are saturated in the red filter band, resulting in a cast to the complementary color, i.e. greenish-bluish. This risk has been taken, in order to obtain better S/N. |

Youtube upload of Perijove-05 animation completed. This is really very promising. A couple of hopefully constructive criticisms: 1 ) you might consider cross-fading between images instead of cutting. There's at least one place where the cutting leaves you with a disorienting black image, I assume because the image coverage hasn't caught up to the spacecraft position. 2) your processing has become quite excellent except for the color. I'm not sure what's going on with the color but I don't think Jupiter is ever that green. Our missionjuno processing just does an auto white-balance after delambertianing and often leaves blue artifacts near the limb and terminator, but not the overall strong blue-green cast. -------------------- Disclaimer: This post is based on public information only.
