Juno's perijove 5 is coming up less than two weeks from now - it's on March 27, 2017.
The target selection voting has started and is open until almost four days from now: https://www.missionjuno.swri.edu/junocam/voting?current A large part of the data volume will be reserved for polar time lapse sequences though. John Rogers has written a helpful summary of the upcoming perijove 5: https://www.britastro.org/node/9377 |

This is a good learning experience for me. If we look at this hi-res IR/visible pair we can see most of the hot spots are in the brown belts as you suggest. However some bluish areas continue into the zones with "suppressed" IR warmings. This suggests to me the bluish areas in the zones are areas fairly cold in IR with thin high ammonia haze, while also allowing us a partially transparent view with scattered visible light into much lower altitudes.
http://www.dailymail.co.uk/sciencetech/art...approaches.html (scroll down page to see image pair and look just right of center in the images) Areas that are dark within the belts look to be the hottest of all, perhaps no clouds are present at all in these locations. Will be interesting if we can see some simultaneous images of the VLT IR data and Juno. The link is showing images from the ESO VLT and ground-based visible light images as a dry run for the Juno observing campaign. A similar situation occurs with satellite images of Earth with thin cirrus clouds. The IR signature looks cold while in the visible it can be relatively dark (blue in color) with the ground still evident. -------------------- Steve [ my home page and planetary maps page ]
