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.

Juno continues to approach and depart from perijove on the nightside of the planet, so we begin and end this sequence again with lightning search images. We will image Io to look for any erupting plumes (volcanoes erupt on Io all the time, but with Juno's unique vantage point we see new eruptions at higher latitudes than are available to earth-based telescopes). The perijove latitude on Jupiter continues to move northward, improving our resolution of the turbulent cloud structures at high northern latitudes and our view of the north circumpolar cyclones.
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.
With some new settings we are able to image Jupiter with the methane filter without getting the annoying artifact in the images, so we are now pushing the images to lower latitudes to find the bounds at which the artifact re-appears.

This is pretty interesting stuff. I knew there were a lot of things that NASA was doing that you could access from their website but it's done far better than I expected.
