There are another three days left over to vote for Perijove-07 points of interest (POI).
This time, all eyes will be on the Great Red Spot (GRS). Provided everything works as scheduled, one RGB image will be made almost above the center of the GRS. I'd think, that this RGB image will be complemented by a methane image. Since this time, we won't have contact with Earth during the flyby, the amount of data to be collected is rather constraint. Therefore, only a small number of images of the polar region is scheduled, just enough for a long-term observation. Storage will be sufficient for imaging several POIs to be voted for, but we may not get a full latitudinal coverage. In order to obtain a full latitudinal coverage of the GRS and adjacent regions, we should take at least one image near the northern and one image near the southern edge of the GRS, better a set of five RGB images. We would see the GRS from different angles, and we would be able to study the turbulence north and south of the GRS. I'd also expect, that only images from north and south of the GRS will be able to cover most of its longitudinal extent. In addition, a sequence of images near the GRS would provide the raw material for a great and unprecedented fly-over movie. That said, there are several other interesting or potentially interesting targets to consider. Besides for an adjacent region of the GRS, I voted for the two polar-most POIs, since I hope, that we'll get some additional polar and subpolar images for a long-term study, and more close-ups of those incredibly turbulent FFR zones near the poles. |

I have been checking DSN Now as early as ~10:00 UTC, and the spacecraft's been downlinking data at a consistent rate of 152.76 kb/s ever since. First using Goldstone, but now the torch has been passed on to Madrid for now.

For those following along, we switched to the 34m net about 10 AM PDT, and this only supports about 30 Kbps. That'll be near-continuous, but I don't think we get more 70m time until mid-day PDT tomorrow.

Expect a partial set of images from PJ7 to show up on missionjuno in an hour or so (posted 07:23 PDT on 12 July.)
UPDATE: images posted as of 07:49 PDT. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

PJ07, #060:
This one ensures, that we have at least something. In this short time, I didn't determine Juno's angular velocity, but adjusted the rotational phase to fit to the model. The PNG version is submitted to the missionjuno site. Now working on the other close-ups, at least for a first version... |

I have to say, the views of the Great Red Spot remind me so much of Pioneer's Jupiter - a pastel-like red spot contrasted against a seemingly clear, while field. Especially this product in particular. It's kinda poetic; Juno is front seat to a Great Red Spot reminiscent of the one its distant spin-stabalised cousins saw 44 years ago.

Jaw-dropping! I know it's huge, but getting the scale right without some marker is still difficult (and this is after a few decades of shrinkages!)
I wonder what Arthur C. Clarke would say.... |

By the way, Sean and Gerald, just thought I'd humour you guys by saying you managed to convert a naysayer about JunoCam today.

My take based on the WONDERFUL work of Gerald
There are amazing details on the clouds inside the GRS, like some convective storms. Also, we can clearly see that the GRS is not like any earth analog. This is as storm, a hurricane, but there are other systems inside. It's like a storm made of storms. -------------------- |
