Voting
Welcome!
Juno is 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”).
Juno’s orbit geometry is evolving so we will carry out campaigns rather than voting on specific targets. Campaigns are focused on a specific science theme and take advantage of the changes in lighting.

What happened to Voting?
Up through PJ8 everyone could vote on their favorite Point
of Interest (POI) and those rounds can be viewed here. Changes in the orbit and mission plan mean
that we are no longer selecting targets by vote.
There will still be a voting page for every orbit and we will describe the specifics of each perijove pass such as the spacecraft orientation. Because of the challenges to predict the Points of Interest that will be in the JunoCam field of view we are now timing the image collection by latitude and/or executing campaigns.

Target Selection
We will take polar images on every PJ pass to assemble
timelapse sequences to study the dynamics of the circumpolar cyclones. Between the north and south pole images will
be timed to get complete latitudinal coverage.
The rest of the resources will be used for campaigns. Options are to look for lightning, take multiple methane images to study high altitude hazes, study Jupiter’s ring, take stereo pairs for cloud altitudes, image Galilean moons when available, etc. We will keep the Voting Round discussion for comments on what would be best. We are hoping that you enjoy being a part of this process, that you enjoy being a member of the JunoCam team.

Voting Round :
PJ5 Encounter
CLOSED : 2017-03-20 16:00:00
Perijove on : 2017-03-27 08:53 UT
The entire perijove pass from the north pole to the south pole will be open for voting. We will however set aside a larger portion of the data volume for polar time lapse sequences to see the circumpolar cyclones rotate.
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.
Once again you have selected our targets! We will be able to image 9 Points of Interest in the priority set by your votes.
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:
Double SEB
Trevmation’s Dark Spot
The Big Red Stripe
String of Pearls + Between the Pearls + An Interesting Band Point
STB Spectre + The White Solid
We are also picking up Covenant 151016 as part of the polar timelapse sequence.
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. Perijove is on Monday, March 27, so we expect to start posting the images on Wednesday, March 29.

So sad, I will not see any Banding Boundary ! My dream will not come true... Perhaps next time...Good luck!
My top three POIs were selected, that´s what I call one lucky round! Now all we can do is wait for the data from our small friend out there..
Thank you for giving us the chance to play a small role in this whole mission!
