Welcome to Discussion
Join the Mission Juno virtual imaging team by helping us to identify what images to capture with JunoCam now that we're at Jupiter!
At each perijove pass, we'll ask you to start voting on which POIs you're most interested in. In the meantime, please participate in the general conversation, comment on POIs identified by the community, or suggest a new feature that hasn't yet been discussed yet.

Hello.
Can you please tell me how far north in latitude the image at
https://photojournal.jpl.nasa.gov/catalog/PIA21641
shows? It's centered on Jupiter's south pole, but I'd like to know the northern extent.
Thanks so much,

JunoCAM is a scientific tool that is specially Designed; Calibrated and Adjusted to take high resolution images from a certain Space altitude while orbiting around Jupiter. Even if is directed to some of those tiny objects they perhaps wont be focused and will be barely visible in some pixel size. It will be not possible to clear; sharpen or focus them with any of the available software. You must know that I am just an amateur and not a specialist or professional, so you might need an assistance from one of those.
Dear NASA; Juno Mission; MSSS;
I would like to clear something here in the Discussion Section. What we are seeing on those images is actually Reflected Light from the Star. On the Computer Monitors we are seeing Emitted Light. Are there any Images from the dark side of Jupiter? If some of those are large Volcanoes is there any emitted Volcanic Lava Light; or Electrical Lightning Light; or other gas or radiation emitted light from Jupiter? Can we and JunoCAM spot them from that space altitude?
I am asking this because and regarding my proposed Concept Tool for calibration and observation. I am presenting to you an explanatory Image with that part from the Tool Concept containing different LCD light emitters and light reflectors.
Jupiter is what we call a gas giant. It is primarily composed of hydrogen and helium, with no surface, just a higher density gas as you go deeper. There are definitely no volcanoes on Jupiter, although its moon Io erupts routinely.
What we see in JunoCam images is light reflected from Jupiter's atmosphere. Trace amounts of methane, ammonia and a variety of hydrocarbons and compounds with sulfur give it the different color clouds. Jupiter has an aurora, so it does have emitted light, but we are not able to detect that in JunoCam images. We do expect to be able to detect lightning but we cannot predict the timing.
As I suspected...! Thank Goodness there are so many Investigators and Key Personnel!... So, the overall Scientific opinion is that what we are seeing with our Human eyes and with our Digital Cameras and Monitors here on Earth is different than what we are seeing in Earth's Orbit, and is way different on the Moon and Lunar orbit; and even more different on Mars and Martian orbit; and so is totally different in Jupiter's Orbit and even the Sun.
And this is so, not only because of the space Distance between the Star and those Cosmic bodies, and the different Light length and wave, but is because those are several totally different Space Environments with different orbit and gravity, that contain different combinations of elements...
I would like to proceed with the clear-out of the Tool Concept. On the presented image are shown the Plates with Earth Elements: Minerals; Rocks; Metals; Alloys. They are by Default. This means that on the image concept is shown only a Grey Color and no particular Earth Element nor Color is chosen; applied; or presented at this stage. The shapes are designed to be different than oval; spherical; or circle shape of a Planet so to not compete with the main observation object. The Types and the Colors of those elements however should be selected from an appropriate Specialists from a qualified governing body: NASA's Materials Testing Laboratory; USGS; NIST; US Mint; or similar.
The Point of Interest of sending such a plates with Earth Elements on the Observation Calibration Tool is that they will show different colors and textures characteristics when imaged in different Space Environment.
There is also a second Point of Interest: when the Craft is traveling into deep space for around 10 Years or more, those Earth Elements can show a sign of interaction; change; or reaction with the Space Environment during the voyage or when orbiting around the distant Planet because the environment will be different than the near Earth orbit.
