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. |

The image from ISIS3 also suggests to me that the problem probably lies earlier in the processing (probably a bad/distorted map for some reason).
However, there was some discussion in a thread here maybe ~2 months ago where ISIS3 was mentioned as part of a discussion concerning optical distortion corrections, the optical axis etc. From the discussion I got the impression that at least until relatively recently ISIS3 probably wasn't handling JunoCam completely correctly - I might be wrong though since I haven't been using ISIS3 to process the JunoCam images (I have been using it mainly for the Cassini images and that's a completely different camera). But in this context it's interesting that I noticed in some of your processed PJ13 images that the images were truncated 'inside' the limb, i.e. a small part of Jupiter very near the limb was missing. At least this was true for images obtained at very close range, I didn't look at other images. |
