Here is a quick and dirty enhancement of image JNCE_2016240_00C06163_V01-mapprojected.png:
This image looks like it was intentionally overexposed to better reveal details near the terminator. One particularly interesting feature is visible near the bottom where clear vertical relief seems to be visible (I don't think this is an artifact). There seems to be an elevated cloud at the terminator - it appears much brighter than other features at the terminator and may even extend to the nightside (I don't know the exact location of the terminator but should be able to determine it later). There is a dark feature left of it that looks like a 'depression' (could also be a dark cloud feature). One thing I find striking about this image and the other polar images is the large number of roughly circular storm systems. I don't know when this image was obtained or at what range. The label file (JSON file) seems to be corrupt and contains no data of interest, just "<Error><Code>NoSuchKey</Code><Message>The specified key does not exist.</Message>..." etc. EDIT: Now I notice that Emily's index page includes the distance from Jupiter, it is 70380 km. I was far too excited about these new images to notice this! |

This image looks like it was intentionally overexposed to better reveal details near the terminator. The label file (JSON file) seems to be corrupt and contains no data of interest... This is one of the aurora search images. (We didn't see the aurora, BTW.) I was hoping that the RATIONALE_DESC field in the metadata would have more detail but it doesn't look like that was done for this release. Keep in mind that this is the first time we've published real data to missionjuno so there are still some kinks to work out. The (admittedly klunky) metadata download worked for me for this image.
