Mostly because none of us know as much about Io as Jason does. I spent several hours on Christmas looking at maps of Io and trying to figure it out without much luck. You'd catch hell for speculating. I know. Wasn't supposed to be an indictment! I'm just more amazed at how many questions were anticipated and answered in a single line. Like Jason's last post... he's repeating himself. |

This is a very preliminary overlay between the JunoCAM image and a basemap. I'll want to actually dig into the raw data to I can be sure that all images are scaled more accurately, but again, shows that the plume is coming from Chalybes Regio. -------------------- &@^^!% Jim!

For scale context, our Moon would have shown 2,5 times smaller from this distance.
I better understand JunoCam capabilties now. -------------------- |

Here's #024, modified from Gerald's drafts. It captures the NEB from an altitude of ~5000 km.
North Equatorial Belt - JunoCam It looks like a moon shadow (likely Thebe's, if it is a shadow) is passing over the cloudtops at center right - this feature is also present in images #022 and #023 and appears to be slowly moving based on its position relative to the dark streamer beside it. Amalthea's eclipse shadow is also visible along the horizon in image #023. |

Wow, you've all been rather busy, while I've been offline a few days!
Here is a link to drafts with the moon images during approach, and of part 2 close-ups. And here reprojections of the close-ups, part 2. Here is a jpg copy of #18: I may continue upload of jpg copies in a few hours. In the meanwhile, you may ponder about possible moonlet shadows in images #22 to #24. I think, the shadow near the limb is real, while another candidate appears to be at a constant location, hence presumably something else. |

Some images from my pipeline. Replaced the perspective camera render in OpenGL that I was using with the panorama camera in Blender. I'm still working on the specific camera settings that I like and will try to automate it as much as possible (I'm currently doing the Blender part manually).
And with a equirectangular panorama: |

Wow, those are amazing! Thanks! And I'm finally able to create an overview strip using Sean's layout: Perijove 17 Jupiter Overview as of Jan 3 2019 |
