It's time to open a perijove-4 thread.
Voting is open for another two days. So, don't hesitate too long. Besides the discussion and the POIs on the mission page, you might consider John Roger's detailed discussion of several interesting features. If everything goes well, all instruments will be switched on. |

As we all know, Jupiter has a visible "surface" that is constantly fluctuating, mainly in that different latitudes rotate at different rates, sliding past one another over time. There is other variation as well, as belts, zones, and features within them shift over time. Therefore, no fixed map of Jupiter can exist.
Here is a map of Jupiter the way it looks now – I provide this as a reference to current Juno observations… and as a shameless plug to my astrophotography. This is based on images I took on March 1, 2, 3, and 9. I previously made a map of Jupiter 11 months ago, and the primary changes one notices in this time are: The North Temperate Zone has changed from white to orange (or: stripes which are more orange than white). Oval BA has shifted a great deal with respect to the Great Red Spot. The pale band feeding into the GRS from its east is extremely turbulent over a large range of longitudes, whereas it appeared very laminar last year. The GRS may be a little more orange (as opposed to more red). This may help people orient towards a few of the features we see in Juno images that are too zoomed-in to show planet-wide context. |
