It's time to start a new topic for Juno's Perijove-09.
Due to solar conjunction, data downlink is delayed several days, but things appear to look good thus far. Data downlink started on October 31, and if everything continues well, it should be a matter of a few days, at most, until the majority of the raw Perijove-09 images will become available. Due to the incremented available storage for JunoCam, we may get a sufficient coverage to render a pole to pole -- well, almost pole to pole -- fly-over reconstruction, despite the difficult communication near solar conjunction. I'll have a try at least, over the next few weeks. |

Perijove-09 inbound RGB images, reprojected, and enhanced. Illumination adjustment is based on PJ-06 TDI-2 images, and may be biased.
I'm elaborating approach and some departure PJ-09 images in more detail, since they are likely to be the only visible light Jupiter images of a major part of its surface available during solar conjunction. Departure images are more challenging to process due to spacecraft maneuvers, and due to the position of Jupiter approaching the left margin of JunoCam's fov, where geometric calibration is particularly tricky. I'll see over the next few days, how far I can get, hopefully over the first two Jupiter days (i.e. 20 hours) after PJ-09, at least. I might find time to infer a PJ-09 specific illumination model before PJ-10, but I'm not yet sure. |

These pictures are convincing me that there will eventually be enormous scientific payoff from the Juno imagery, despite the official disclaimers. The still images alone speak to the dynamics taking place, and in concert with the deep-looking radiometry and lower-resolution images from Earth that provide greater temporal coverage, seemingly must speak volumes to the atmospheric dynamics at large and small scales.
And also: They are stunning! You amateur image wizards are working wonders. |
