Today is Jupiter Orbit Insertion (JOI) minus 180 days. 53.5 days after JOI, Juno will make its next close pass to Jupiter, and that's when we expect to get the first good images from Junocam, although there may be some imaging during approach and earlier on the first orbit.

Even if Juno doesn't take many images during approach, the other instruments will be active to detect entry into the magnetosphere, correct? Any idea when that would happened (I know the magnetic field is gigantic, but not sure exactly how large).

Using some rough math, I would say late March on into April there should be some detection of the magnetosphere.

Juno does plan to take some images during approach. They have to turn off all the science instruments 5 days before JOI.

Juno does plan to take some images during approach. Certainly, but at a range of 5.2e6 km on JOI-5d, Jupiter is about 40 pixels across, so they won't be great images. [Junocam, maybe JIRAM does better.] Handy formula: Junocam Jupiter size in pixels ~ 210/d, d in millions of km -------------------- Disclaimer: This post is based on public information only.

Juno just set a new record for solar power distance, beating out Rosetta's hibernation phase. Very impressive!

Juno performed TCM11 yesterday. All went as planned. Juno is now aimed at the Jupiter insertion point!

BTW, I ran across this technical description of JIRAM -- http://www.ifsi-roma.inaf.it/jiram/downloa...Tech%20note.pdf -- that has some detail about how the instrument works. Its IFOV is about 2.8 times finer than Junocam's, so at JOI-5d Jupiter should be about 112 pixels across.
I haven't seen any inflight imaging from JIRAM yet. According to http://www.lpi.usra.edu/opag/jul2013/prese...o_efb_plans.pdf images were supposed to be taken of the Moon during EFB. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

A Google tabular site has been created that displays observations planned by the Juno investigations, together with Earth-based supporting observations: https://www.missionjuno.swri.edu/planned-observations.
This will be regularly updated by the Juno science team and by the supporting observers. |

Back from the Côte d'Azur in France, I see that the PDF versions of most of the talks of the Europlanet workshop: "Juno Ground-Based Support from Amateurs: Science and Public Impact", are already online.
Most of the sessions have been recorded by video. Providing the recordings online is pending. (As a personal note: This has been a rare opportunity to find out that people you otherwise know only virtually via web are actually real! It seems, most of the participants shared this experience. Thanks to the orga-nice-rs, who made it possible! ) |

Nice pics, Looks like you had a great time with like minded people.
You are right, it's always nice to match a face with an online 'personality' |

Entering 'Jupiter space' (by the standard of gravitational influence) https://www.missionjuno.swri.edu/news.
Crossing the magnetosphere should be soon as well, I'm assuming? If the instruments are on they should detect the transition. |
