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 will be oriented such that the High Gain Antenna points to earth for a gravity pass. That means that the JunoCam field of view will be slightly offset from nadir.
We are continuing to test various modes of the camera so we will only be able to include 1 - 3 targets selected by the public. This should be the completion of camera testing, so that on PeriJove 4 (PJ4) we will welcome public input for all the images we take crossing through perijove.
The number of images we take is limited by our onboard storage. Each picture requires a different amount of data volume so in general we will take a different number of images every PJ. We will rank the selection by the number of votes you cast.

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 results are in! We are still testing the camera settings so we limited our choices from the public vote to 3. At PeriJove 4 (PJ4) we will open up the entire set of possibilities. Our winners from this round are POI NCC 1701, String of Pearls, and Weird Dark Spot.
We are in a unique situation this time because we have limited planning data to go by. Jupiter has been very close to the sun, so our amateur astronomer inputs are not as longitudinally complete as usual, so the cylindrical map that we identify viewable POI's on is not as recent as we'd like. The winds in Jupiter's belts and zones move at different speeds and directions, so predicting what will be in our field of view was challenging. We will schedule the images so that we should see our winners, but we will be as curious as you to see if we actually capture them!

osm!
Shout-out to everybody from the r/junomission subreddit that voted! :D
In the future, if you are wishing for a particular location, please make sure we have a POI in that spot!
weird dark spot because it sounds suspicious and stands out the most, hmmmm...
Here is an example of an oblique angle shot from the space station.
I'm voting for the south equatorial belt just downstream of the great red spot. This is the POI closest to the equator. As the probe gets closer to the equator the altitude gets lower and the image resolution should get better. We've never seen Jupiter at the kind of resolution which the probe is capable of at closest approach. This is an opportunity to see something new.
What I'd like to see probe do is take a horizon to horizon shot at this location. The zones clouds are at higher altitude than the belts, so looking north and south there should be walls of clouds at the transition from belt to zone. Looking toward the horizon there is a good chance of spotting high altitude clouds or haze layers. Jupiter has a number of chemically reactive elements in it's atmosphere and when UV light hits that brew then it is likely to form chemical compounds which condense into haze.
Some of the nicest pictures from the space station are oblique angle spots looking towards the horizon. I think that a similar angle should also work for Jupiter.
Happy days ahead!!!!
There's a long string of suggested POI in 35° south area. Which one would be the most shallow angle, ideally imaging the limb of Jupiter?
So excited!
Hello. Would it be possible for Juno to observe/capture images of lightning storms? Many thanks. :)
i will go with the black patch
I'm with Candy regarding the area in the SEB in the wake of the GRS - always so dynamic with the interacting whorls. No strong preference on the other features, although something at around 41N would have been nice, per John's suggestion.
If I could suggest a list of priorities for imaging at perijove-3, they would be:
1) The NTBs (24 deg.N, planetographic). The great outbreak on the NTBs jet is still evolving and won’t be in this dynamic phase again for the rest of the mission, so this is a unique chance to image it at hi-res – at any longitude. It’s not marked as a POI but I hope image(s) will be taken anyway.
2) The SEB rifted region (marked as a POI -- I will vote for it): This may be the only opportunity to image this region from Juno; it is usually very dynamic, and the images might catch an erupting plume, perhaps even with cloud shadows?
3) Possibly, NN-LRS-1 (41 deg.N, planetographic), which should be around L3 ~ 6. However it has not been imaged yet this apparition (a good methane image is needed) so this longitude is +/-34 deg, and it’s not marked as a POI.
(By the way, on the predictive map I just posted, longitudes of major features and the extremities of the Juno track are +/- several degrees, and of course minor features may have changed.)
--John.
In an attempt to predict what features will be where during perijove-3, I have posted a predictive map for perijove-3 on our BAA Jupiter Section web pages at:
https://britastro.org/node/8411
--John Rogers.
To anyone who suggests POIs, remember they are more likely to get chosen if you have some sort of historic or scientific information paired with it.
I am going to vote for the POI just west of the Great Red Spot - that area is always so dynamic and interesting!
I suspect all features poleward of 50 degrees latitude in both hemispheres will be imaged by JunoCam as a part of the polar coverage that will take place in any orbit. So I'm going to vote for features in the +-50 degree range
