My YouTube version of the GRS fly-over is online now.
Here is the site where I'll provide the stills, currently with dangling hyperlinks, except the AVI. The stills are about 6 GB of zip files. My upload bandwidth is usually about 100 kb. Considering several system shutdowns during the upload, including some intentional breaks, I'd expect, that the upload will be completed near 2017-07-17T00:00:00, i.e. in about one day from the time of submitting this post. |

The zip files 61_1, 61_2, 62_0, and 62_1, i.e. the last four are uploaded, thus far without technical issues. If everything continues the same way, the remaining zips should be available today, 2017-07-16, at about 16:00 UTC.

Here is a re-timed video using your files Gerald.
Music is Lux Aeterna by György Ligeti I did a little processing and disguised the linear path change. My time was limited so the transition around 15s could be better! -------------------- |

Upload completed.
I've also added an MP4 version, sampled with 50 fps, by frame doubling, I guess, simply used the ffmpeg default. "Lux Aeterna" has been one of Glenn Orton's suggestions. My vote goes to another of his suggestions, "Also sprach Zarathustra", the most famous "2001" sound for the most famous Jupiter feature, applied to a 10-fold time-lapse, hence a 2.5-fold slow-down of my version. |

That's gorgeous! You get a feel for the immense scale of this planet. I love the Ligeti for its raw energy, and probably also for its association with some other classic film about space.

So, a person on the subreddit wanted to know what this particular dot in Bjorn's image could be. I don't have an answer for him, so I'm asking you guys on his behalf. Just an artifact of processing or something like that?

So, a person on the subreddit wanted to know what this particular dot in Bjorn's image could be. Looks like it's an uncorrected artifact from the crud on the image sensor. There are some charged particle hits in these images but this doesn't look like one to me. It's always a good idea to go back to the raw data in cases like this. Things that show up in only one color are usually one of these two things. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

In my patched version of PJ07, #60, there is the same bright pixel, and I try to patch even very subtle camera artifacts, based on PJ06. So, it's either a new hot pixel, a rare coincidence of artifacts that I don't patch, or an "event".
The by far most likely option for an "event" is an energetic particle hit. There is a remote chance for a lightning, but since it appears to be just one pixel, I doubt it. |

At least some of the PJ7 images are a bit noisy. That's the reason for a few strange pixels in my images; I haven't succeeded in fixing all of them. This is negligible compared to Galileo and Voyager but my impression is that the PJ7 images are probably more noisy than the PJ6 images. Here is an example from the raw data, enlarged by a factor of 3:
I suspect these are radiation hits because the number and position of these artifacts differs from image to image. |

Here are approximately true color versions of PJ7_61:
And some of the relevant metadata: IMAGE_TIME = 2017-07-11T02:10:42.286 MISSION_PHASE_NAME = PERIJOVE 7 PRODUCT_ID = JNCE_2017192_07C00061_V01 SPACECRAFT_ALTITUDE = 13917.4 km SPACECRAFT_NAME = JUNO SUB_SPACECRAFT_LATITUDE = -32.6733 SUB_SPACECRAFT_LONGITUDE = 60.7938 TITLE = POI's: Lower Great Red Spot Atmospheric Flow, Fractured Boundary Resolution at nadir: ~9.4 km/pixel |

Wow, beautiful. The redness of the GRS makes it look more like your usual enhanced color composites.

Its amazing how Jupiter Red Spot looks more like the Pioneer 10/11 Images.

Hi All -
Newbie here. I've visited site many times, in the past. Fantastic processing work by many of you. A Q please. I've created a rough Anaglyph using GRS pass images but haven't seen any posted elsewhere. Do any of you know whether a correctly processed image (corrected for camera, motion etc distortions) in 3D is forthcoming from the Juno team? Thanks |
