Cylindrical Map

We use images from amateur astronomers (uploaded on the Planning page) to create a new cylindrical map every 14 days. This is the latest one! We have identified long-lived storms as Points of Interest (POI’S) and invite you to share your thoughts about them.

Notes about cylindrical maps and perijove passes

In its 53-day orbit, Juno spends most of the time distant from Jupiter. The spacecraft swoops from the north to the south pole in just 2 hours, which we call a "perijove pass".  That means that the close-up images JunoCam can take are restricted to just a swath of longitude, not the entire globe.   JunoCam points out along the solar arrays, and for most perijove passes the solar arrays are oriented to the sun, so JunoCam is pointing 90 degrees from the sun.

As time goes on Juno’s orbit is moving around Jupiter.  The most distant point of the orbit is moving to Jupiter’s night side.  Perijove (“PJ”), the closest point in the orbit, is moving more to the sun-side, which impacts JunoCam because this moves Jupiter off to the side of our field of view.   A simple comparison of the images collected at PJ9 to PJ10 in the Processing gallery shows how the geometry is changing the shape of the images.

For those of you who have been participating since the beginning, we initially used this page to identify Points of Interest (POIs).  We would then vote on which POI’s to take pictures of on any given perijove pass.  This was a concept that we developed for Juno’s 14-day mission plan.   The decision to stay in a 53-day orbit means that the viewing geometry changes more and this impacts our ability to predict what will be in JunoCam’s field of view.   (To see the POI’s that were selected in the past you can go to the Voting page.)

    The zeta function and Rheimans hypothesis, plus color theory and the speed of light mean earth and mars are the same at different points in time, can anyone hear me? NASA I’m trying to help. I have the equations you need but you won’t open your eyes

    Thank you for accepting my request to join. I just read an article about the moon, lo. Under 1000 miles close? Amazing! Fascinating!

    From the Image Processing Welcome message at


    JunoCam is now showing the effects of that radiation on some of its parts. PJ56 images show a reduction in our dynamic range and an increase in background and noise. We invite citizen scientists to explore new ways to process these images to continue to bring out the beauty and mysteries of Jupiter and its moons.


    Being part of the JunoCam image processing community, gaining a clearer understanding of the challenges would enable us to enhance our image processing techniques. Transparently sharing technical details, insights, and ongoing analysis from the project would boost our efficiency and improve our ability to devise effective workarounds.

    The following image compares green channel PJ55_72 transformed with a very preliminary model of the image corruption issue with PJ56_191 raw data:

    Data from recent orbits include "marble movie" images which use only two color filters, Blue and Red. What is the motivation for using two filters instead of three? And can you discuss how these long image sequences are used by the project.
