Nearly all of the PJ21 images are on missionjuno now -- one image is still partial AFAIK.

I noticed that there is no image number 33 at the MissionJuno website. Is that the one that is still partial? If there is an image number 33 that's actually probably a very interesting image that should show areas north and/or west of the GRS very well.

With a linear decline in width up to Perijove 18, then a sharper decline to Perijove 21 which matches the timing of the detachments observed by Damien Peach.

Something comparable has also been measured from ground based images, see http://alpo-j.asahikawa-med.ac.jp/kk19/j190624r.htm and http://pianeti.uai.it/index.php/Jupiter:_2019_Animated_gif

Correct. Image 33 taken 04:32:27. The dropout is small but goes right across the GRS in one channel (of course.) I'd expect it to be pushed by mid-week next week one way or another.
