Here is an 8x enlarged draft of Io in PJ16, #01:
Here the other drafts of north polar PJ16 images. The north polar images have been designed to obtain good data of the northern circum polar cyclones (CPCs), and in order to get data as close to the pole as possible. We hope to be able to retrieve information about the dynamics of the CPCs. Due to solar conjunction, the amount of data for PJ16 is limited. The instruments of the spacecraft were looking close to the ground track, without the HGA antenna pointing to Earth during flyby. For JunoCam, the overall focus is on good close-up images. Only few approach and departure images have been taken, actually no approach or departure sequence. |

A montage showing the PJ16_6 image in approximately true color/contrast (left) and with the effects of the varying illumination removed and the contrast increased (right):
Areas near the limb at lower left are overexposed since the exposure time was increased to better show details in the dimly lit areas near the north pole. A subset from the metadata: IMAGE_TIME = 2018-10-29T20:29:09.835 MISSION_PHASE_NAME = PERIJOVE 16 PRODUCT_ID = JNCE_2018302_16C00006_V01 SPACECRAFT_ALTITUDE = 47405.6 km SPACECRAFT_NAME = JUNO SUB_SPACECRAFT_LATITUDE = 81.6117 SUB_SPACECRAFT_LONGITUDE = 137.4188 TITLE = PJ16 North Pole at Minimum Emission Angle Resolution at nadir: ~32 km/pixel |

The next six images from Perijove 16 are up on missionjuno, it seems!

Here is a draft of #08:
Note a presumable lightning on the night side close to the terminator, and the visibility of Io's night side. Here more drafts of part 2. Here a more complete set of reprojections, part 2. Here several map products of part 2, approximately illumination adjusted, and stretched to gamma=1 relative to radiometric values. Reprojections, part 1. Maps part 1, with gamma=1. Maps part 1, with gamma=4. |

This is almost vertigo-inducing, but in a good way.
I feel safer than ever in saying that these images will produce important science related – at the very least – to the chromophores in Jupiter's clouds. |

Link to drafts and reprojections of PJ16, part 3.
It's five new images. I'll provide JPG copies of the reprojections here. #14: |
