Did anyone happen to observe Jupiter immediately before 2018-07-16T03:47:30 plus light travel time, especially recording a video?
I'm not yet quite sure, But we might have had a small (double?) impact on the night side of Jupiter's north polar region. Admittedly, it's hard to observe Jupiter's night side from Earth, but maybe there are preceding or follow-up observations, or there has been another presumed event on the dayside at the same time. |

Exciting way to start perjove 14. Images from your processing pipeline starting to come out tomorrow?

I'll start processing as soon as the raws will be posted on the missionjuno website. This requires a full set of SPICE kernel files (which I guess will get available near midnight UTC), and depends also on the pipeline at MSSS and the website operation. But I'm confident, that we'll see first images early tomorrow UTC. Maybe someone can beat me?

Below are very early, quick and dirty images processed from PJ14_20 ("PJ14 Jet N5"). I'll post improved versions later with better color alignment and slightly higher resolution. First approximately true color/contrast versions:
And enhanced versions:

It seems the Hubble was looking around the Jupiter system for Prof. Denis Grodent a bit after that time, maybe it'll have caught something? -------------------- |

I'm working on that. But I'm tired after a 27 hours day by now. After posting the set of reprojected images, I'll provide some context, at least.
Most of the RGB images available thus far, approaching from the north: #06, #08, #10, #11, #13, #16

Now some context of the blips in raw images:
I'm going to work on map products, such that it will hopefully be possible to see, whether the blips were at the same position in both images, if projected to Jupiter. |

Thanks for all your efforts Gerald...
 Details... 22  21  20  19  18  Here is a detail from PJ14_22 made with Matt Brealey's pipeline...  and a preliminary output from Brian Swift's pipeline...  -------------------- |

Those are funtastic results, Seán!
Here a more complete set of reprojected images. And drafts without shape model nor trajectory, therefore misaligned for close-up portions. In the set of drafts, note especially #22, with its distinct transparent bluish atmosphere layer along portions of the left (in the image) limb. Here a 10-fold enlarged and enhanced crop hinting even towards a haze horizon in the upper atmosphere:
