I barely dare to ask, whether JunoCam has been powered on between October 15 and 19, and whether it has taken images during this time...

Nope, we didn't get to the first image before the s/c safed.

Here 20 PJ1 inbound methane band images:

Maybe it's possibe to find, or to rule out, an early state of the new features in the methane images near PJ1.

Browsable version of the last/latest 41 RGB Marble Movie level-1 images, covering about two Jupiter days.
The next sequence of images has been scheduled to get a different name, but with the postponed period reduction maneuver (PRM) we'll see.

Marble Movie, parts 1 to 14, the whole scheduled sequence from PJ0 to PJ2, skipping PJ1 close-ups, is available as level-2 processed AVI animation (about 32 MB), and also as a MOV version (about 350 MB), converted from the AVI. A small number of frames are omitted.
I've provided a few additional short 14-image animated gifs with strongly motion-enhanced stills, time-lapsed with about 10 hours per frame, covering the week of part 14, differently shifted in rotational phase. Those are intended for Jupiter experts, who try to see effects of the recent outburst.

I've uploaded the Marble Movie, part 1 to 14, to YouTube. It's almost all Marble Movie RGB images between PJ0 and PJ2.
And a 1500-fold time-lapse of the PJ1 approach, until Juno has been almost exactly over Jupiter's north pole, each still a weighted mean of reprojections of two mostly consecutive JunoCam images, 20 Marble Movie images, and one PJ1 image. The PJ1 image is #C6162, hence skipping the longer-exposed #C6160 of similar perspective. The stills are square-root encoded like the raws, but with linear weights for the color channels to get closer to the "real" colors.
I've submitted both videos to the missionjuno site.

Here a short status update of my attempts to create de-lamberted Marble Movie maps.

Similar method (approximately de-lamberted planetocentric cylindrical partial maps, stretched by 4th power) applied to another 42 images (40 Marble Movie images, and 3 PJ1 images, including the one already processed before), north to the right. I've also provided the square-root encoded version (without de-lamberting), and the applied approximate de-lamberting mask.
These drafts bring out quite some detail. But they show various issues, too. I'll pick out some color calibration, first.

Edit: Crops of #6180 and #6189:

I'm inclined to see dynamics beyond possible errors in the map projections.
(Images have been taken around 13:19 and 19:15 on 2016-08-27.)

This is an attempt to check for subtle changes between images #6159 and #6160, the transition from the Marble Movie sequence to PJ1:

The frames are crops of approximately de-lamberted and enhanced (by 4th power) map-projections, north to the right.
