Voting
Welcome!
Juno is now in a 53-day orbit. When it passes close to Jupiter (“PeriJove” or “PJ”) we will take as many pictures as we can. The number of pictures that we take is limited by the amount of onboard data storage that we have for JunoCam, so we have to be selective. The images are collected as we go from the north pole of Jupiter to the south pole, which happens in a brief 2 hour portion of the orbit. On any given perijove pass we will only be able to image targets in a narrow swath of territory the spacecraft flies over (“groundtrack”).
We are inviting you to participate in this selection process. Each perijove we will tell you if there are any special constraints, special opportunities, or unique goals we are trying to meet. We will set aside data volume for 2 polar images. Then we will invite you to prioritize the points of interest, and we will image as many as we can, based on your priorities.
There will be a voting page for every orbit and we will highlight the Points of Interest (POI’s, defined on the Discussion page) that will be within the JunoCam field of view. Voting will usually be open for 6 days, although that schedule may be modified for holidays. The number of votes that a POI gets will determine its priority. Your comments, your advocacy for a particular POI, will help to get it selected!

Voting Rules
Target Selection
The target prioritization and selection process is ordinarily done by an imaging science team in a conference room or on a telecon. Each scientist argues for their top candidates and says why they are important.
In general we are holding back enough data volume for 2 polar images. Occasionally we will also set aside some data volume for a unique image of a Galilean satellite. All the rest of the data volume will be used to target images in the priority determined by the voting.
You will be a participant in the discussions we would otherwise have off-line. The Juno science team will be weighing in with their wishes, but they will have to advocate and convince you to vote for their favorites. We are hoping that you enjoy being a part of this process, that you enjoy being a member of the JunoCam team.

This will be the first time we open up the complete perijove pass for images you select. BE SURE if you have a candidate that you have entered a POI for it! We go by votes, not by sites suggested in the comments. On every pass we will take an image of the north pole and an image of the south pole. The rest are up to you! The spacecraft orientation is what we call "MWR-nadir". It is optimized for the MicroWave Radiometer instrument so the effect is to point JunoCam at the groundtrack below the spacecraft, not offset to the side.
About Perijove Predict Maps
Every perijove pass we have the challenge of predicting where Points of Interest will be as the different zones of the planet have different wind velocities. This map shows our effort to rotate the latitudinal zones with their different wind speeds to predict what will be under the Juno groundtrack.
The votes are in! We will be able to image the top 10 in the priority set by your votes. In addition we will pick up 5 others because they are close in latitude to the top vote-getters. This assumes of course that the we have done a good job in predicting the wind speed at each latitude, and where the points of interest will be. Our top vote recipient, Oval BA, is right on the edge of where we predict we will be able to image, so we have our fingers crossed that we will get that one.
We started the process of generating image commands as soon as the voting closed. We looked first at the predictions of what time an image would need to be taken to get a particular POI. We have constraints on how closely together we can take images, because an image must be moved from the camera to the spacecraft computer before we take the next one. That means if targets are closer together in time than 90 sec we combined them. We took the time that corresponded to the higher priority target, but we will get the other POI's in the image.
We then started planning images in priority order until we used up all the available data volume.
The list of POI’s we will image in order of the votes they received is as follows, with the “+” indicating targets we combined:
Oval BA
Structure01 + Outbreak!
The big red stripe v2
Turbulence + Hotspot
The wonderful south pole
Dark spot in turbulence + White spot Z + Band transition
North pole on Jupiter + Darker skies
Cap of Jupiter
Dark spot
Jovian antarctica
These images will be available after we get "C kernels" which is a file with the spacecraft orientation as a function of time. This data is necessary for us to process the data before we put it on the website. It takes two days for us to get that data from the navigation team. Since that is a Saturday we will begin running the data through our pipeline on Monday.

Too short a round. I just found out about this and I wanted to participate, only to find that voting is already closed.....
LIKE TO KNOW THE MOST CLOSEUP PHOTO OF THE SURFACE
Is there any way you can position the camera to get a look back of earth? Or how about two shots taken at two different time to show just how fast the spacecraft is traveling.
