About This Round
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.
Perijove Predict Map
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.

Winner Selection
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.....

    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.

  4. comment by Clerambault-58 on 2017-01-23 10:59 UT

    I voted for the pole edge shot. Someone else vote for the dark turbulence becuase maybe it will see down into the planet as a void.

    Uhhh... wasn't voting supposed to be closed 4 hours ago? The "Closes in:" counter on the page has been stuck on "0 days 2 hours" for quite a while now... ( ̄~ ̄;)

      North Pole!

    • comment by Sage-Nickle on 2017-01-22 17:48 UT

      Hints of several interacting physical processes make the spot-band transitions attractive.

    • comment by Palmaria-19 on 2017-01-22 04:56 UT

      I agree, the poles!

    • comment by Ingwelde-87 on 2017-01-21 23:32 UT

      Lets see what those poles look like!

    • comment by Marco on 2017-01-21 21:59 UT

      I think that the north pole is the most interesting part.

    • comment by Esseff-53 on 2017-01-21 20:54 UT

      Only Juno can see the poles, so we should concentrate on imaging there. Our only chance for a long time! We can image other parts with other resources.

    • comment by Raywilson-17 on 2017-01-21 08:05 UT

      I also voted for Oval BA.

      I'll be thankful for whatever though.

      Keep up your good work!

    • comment by Ixian on 2017-01-20 23:08 UT

      Went with big red stripe.

      Why does this one band apparently encircle the planet so uniformly?

      Also, I'm wondering if Jupiter's clouds and stripes are influenced by the tidal pulls from the major moons.

    • comment by Silvain-60 on 2017-01-20 17:24 UT

      I believe viewing the transition areas between bands is critical. We have a general understanding of how and why the differentiation occurs, but a more detailed understanding could be invaluable for unraveling the mysteries of the many layers of Jupiter's atmosphere!

    • comment by Misik-48 on 2017-01-20 14:53 UT

      To be quite honest any pictures have all my interest, including all of your hard work and dedication of all those working at NASA to make this even happen! THANK YOU!!!

    • comment by Robert on 2017-01-20 10:22 UT

      Why is there just one big red spot and a lot of small one's.

      • comment by Barklajdetolli-09 on 2017-01-20 06:04 UT

        I'm sure it would be difficult to capture good imaging of the north and south poles, but that would be lovely.. Otherwise I think the most interesting location of study would be the Oval BA.

      • comment by Covichi-35 on 2017-01-20 04:58 UT

        My 3 choices: Dark band, dark spot in turbulence & sting of pearls! Thanks for letting us vote!

      • comment by Wespa on 2017-01-20 04:44 UT

        String of Pearls can be flying objects! Vote! =)

      • comment by Oberth-79 on 2017-01-20 04:12 UT

        Thank you NASA for letting us vote on where Juno points its camera! Now we can affect space and time! JK just space.

        This is so great. Thank you Nasa - Juno.

        Noticed after I voted the happy coincidence that my choices are more equatorial so closer to perijove and so better "surface" resolution.

      • comment by Kunqu-15 on 2017-01-19 20:06 UT

        Thank You NASA And Juno

      • comment by Nishi-koen-97 on 2017-01-19 19:55 UT

        Love that we can vote ♡ exvited to see what outcome is

      • comment by Tom on 2017-01-19 19:38 UT

        I can't argue with Candy's selections! For my own part, i've put my votes with Oval BA, because it's our first chance to image massive red storm system. We may not get it, it depends on the drift speed, but there's a chance we can capture it. My second vote went to Outbreak! because this is a brand new outbreak of clouds in the South Equatorial Belt and we're flying right over it, so we should be able to get stunning images of a recent disturbance. Finally, I voted for HotSpot, because we have a chance to directly image at high resolution what is known as a '5-micron hotspot', generally a downwelling hole in the clouds often thought of as a kind of Jovian desert, very like the one that the Galileo Probe descended into. Again, we don't really know what will be there when we snap the picture, but we'll be flying right over, so worth a shot!

        So those are my (current) votes. Remember, you can change your mind right up until the Voting Round closes! Get your votes in and let your voice be heard!

        • comment by Altdorfer-68 on 2017-01-19 19:33 UT

          white spot z got my 1st vote

        • comment by Candy on 2017-01-19 15:18 UT

          Philosophia-47, thank you for your insights. My 3rd vote goes to the Big Red Stripe. The idea that we are looking at a new belt is very interesting - what will that look like at high resolution? What will we learn about its dynamics?

        • comment by Candy on 2017-01-19 15:13 UT

          I am also going to vote for Hot Spot. This is the type of place that the Galileo probe descended into many years ago. This is our first opportunity to get a close-up shot of a very unusual place in the atmosphere.

        • comment by Candy on 2017-01-19 15:09 UT

          It's a tough choice this time! I like what John pointed out about oval BA. We may miss it if we are off on our wind velocity at that latitude, but the turbulent area just to the east is sure to be interesting - so oval BA gets one of my votes!

        • comment by Bhuiyan-24 on 2017-01-19 02:08 UT

          I want to know all about planets .i m a fresher now

        • comment by Philosophia-47 on 2017-01-19 02:04 UT

          I'd like to offer the following list of suggestions, in order of priority. Details are on our BAA Jupiter Section web site at:

          [This was posted on the main 'Discussion' page before I realised that it should have been here - apologies for the duplication.]

          1) The NTB(S) – the new orange belt. [POI: ‘The Big Red Stripe v2’: latitude +22.7 centric.] A unique opportunity.

          2) The disrupted NEB north edge. [POI: ‘White Spot Z’ (lat. +14.3)] These latitudes are currently very disrupted from both the NTBs upheaval and NEB outbreaks.

          3) The new mid-SEB outbreak. [POI: ‘Structure01’ (lat. -13.75)] Another unique opportunity to catch an exciting phenomenon!

          4) Oval BA and currents east of it. [POI: ‘Oval BA’ (lat. -32.7)] Oval BA may be too far from Juno’s track, but Juno will get a good view of the region east of it which has tended to produce new circulations in recent years.

          5) SS-AWOs [3 POIs: ‘String of pearls’]. The anticyclonic white ovals of the S.S. Temperate domain.

          6) NN-LRS-6 [POI: ‘Small white storm’(lat. +36.25 c)]. A beautiful oval, but very like NN-LRS-1 which was imaged at PJ-3.

          Looking forward to seeing the results! --John Rogers.
