There are another three days left over to vote for Perijove-07 points of interest (POI).
This time, all eyes will be on the Great Red Spot (GRS). Provided everything works as scheduled, one RGB image will be made almost above the center of the GRS. I'd think, that this RGB image will be complemented by a methane image. Since this time, we won't have contact with Earth during the flyby, the amount of data to be collected is rather constraint. Therefore, only a small number of images of the polar region is scheduled, just enough for a long-term observation. Storage will be sufficient for imaging several POIs to be voted for, but we may not get a full latitudinal coverage. In order to obtain a full latitudinal coverage of the GRS and adjacent regions, we should take at least one image near the northern and one image near the southern edge of the GRS, better a set of five RGB images. We would see the GRS from different angles, and we would be able to study the turbulence north and south of the GRS. I'd also expect, that only images from north and south of the GRS will be able to cover most of its longitudinal extent. In addition, a sequence of images near the GRS would provide the raw material for a great and unprecedented fly-over movie. That said, there are several other interesting or potentially interesting targets to consider. Besides for an adjacent region of the GRS, I voted for the two polar-most POIs, since I hope, that we'll get some additional polar and subpolar images for a long-term study, and more close-ups of those incredibly turbulent FFR zones near the poles. |

A bit late to the party but here are my versions of the PJ7_60 image. As I usually do I decided to break this up into three separate images to get something similar to what one would obtain with a regular camera at Jupiter. To show Jupiter from limb to limb requires a *very* wide field of view, much wider than a typical camera has.
These are approximately true color/contrast views. The only enhancement is that I sharpened small scale features a bit, mainly to compensate for the resampling that occurred during some of the processing steps. These images have the same resolution in km/pixel as the original framelets. And the associated metadata for image PJ7_60: IMAGE_TIME = 2017-07-11T02:07:07.724 MISSION_PHASE_NAME = PERIJOVE 7 PRODUCT_ID = JNCE_2017192_07C00060_V01 SPACECRAFT_ALTITUDE = 9866.1 km SPACECRAFT_NAME = JUNO SUB_SPACECRAFT_LATITUDE = -24.4222 SUB_SPACECRAFT_LONGITUDE = 58.2555 TITLE = POI's: The Great Red Spot, Edge of Great Red Spot, Within the Wake of the Great Red Dot Resolution at nadir: ~6.6 km/pixel Murphy's law struck during the processing. Windows decided that it would be a good idea to reboot my machine about 30 minutes after I went to sleep last night. At that time my machine was running 6 instances of the software I use to process and reproject the raw framelets. This delayed everything by at least 5-10 hours. I thought I had managed to completely prevent these unwanted reboots but no - they still happen but now only on rare occasions (in particular occasions when I absolutely don't want them...). |
