Juno perijove 9, October 24, 2017, near solar conjunction Options

In the meanwhile, John Rogers released two reports about Perijove-09:

Juno at Perijove-9 (Part I): Global maps, and
Juno at Perijove-9 (Part II): What the close-up images show.

Despite the difficult observational conditions, we were able to create a global cylindrical map.
Of particular interest is a newly formed south tropical disturbance near the GRS.

The Atlantic posted an article today by Marina Karen titled The Photoshoppers Behind Dreamy Jupiter Photos, which quotes members Gerald Eichstädt, Seán Doran, Björn Jónsson, Roman Tkachenko, Emily Lakdawalla, and Jason Major (listed in the order mentioned).

A bit belated, but congratulations to you all for this article and recognition! The Atlantic is a widely-distributed US magazine. The article also name-checks our 'no-frills' Forum.

Well, UMSF has been playing an important, if not essential role in bringing people together.

Here a link to a Perijove-09 flyby animation.
The link is submitted to missionjuo, too.
I've implemented a "nadir mode" for cylindrical views. This helps to make the movie's horizontal center continuously pointing to Jupiter's center. Vertical displacement is allowed in order to fit with JunoCam's fov. For the youtube version of the movie, I've chosen half second blendings, since the alignment of the scenes isn't quite perfect, and would hence result in doubled features over too long periods of time.

I'll try to upload stills, and mp4 files onto the junocam.pictures webspace later tonight (CET).

Another excellent effort Gerald! I think this sequence really sells how close Juno gets to Jupiter. I hope the tweening software can handle the closer frames without too much trouble.

This is so cool Gerald! Here is my humble attempt at a more poetic rendering of your animation:

Thanks! I like that sound track of Vangelis, Avisolo.

The stills are online since a few hours; the online version is compressed to 1.7 GB of JPG files, I've used 98% quality in order to save upload time and storage volume, and to maintain good quality.
I've rendered two movie versions, one with short blending for Youtube upload, and another one with long blending resulting in an overall more continuous impression, but with considerable feature doubling.
The individual scenes before blending are provided as MP4, as well.
The MP4 scenes have been rendered from BMP files, the same files the JPG stills are derived from. Each of the BMP files has been rendered directly from the respective raw files in one monolithic step using double precision floating point arithmetics.

Thanks Gerald!

I've replaced the original video with the files you uploaded, makes for better viewing:

[Gerald]

Beautiful! I've recommended it via email to several members of the JunoCam team.

[Sean]

It appears that these animation renders are reversed/mirrored. Can you confirm this Gerald? At least when compared with the initial processed stills.

[Gerald]

You are right, the cyclones are winded in the wrong sense. I should have noticed that. I'll try to mirror the movie. The stills will remain as they are.

[Sean]

It's easy enough to correct, I just wanted to make sure you knew.

[Gerald]

These things can happen, especially when I'm working around the clock. Thanks for your checking!

The flip-corrected version is on Youtube, now.
The previous version on the missionjuno site hasn't been approved yet. So, I've removed it and added the revised version, instead.

Here is an early pass on Gerald's video [flipped, rotated, variably retimed & processed] set to 'Orphic Hymn' by Jóhann Jóhannsson
