Can anyone explain the complete lack of coverage of Juno's Perijove 9 flyby of Jupiter? Each previous perijove pass was widely covered on the Internet, but I have been unable to find any images or information about perijove 9, which took place a week ago. Images from perijove 8 had already appeared a week later.

At first, I thought it was something to do with Jupiter's solar conjunction (when the transmissions are disrupted), but that can't be the explanation: conjunction took place shortly before perijove 8, without any apparent delay in the processing of the images early in September. So why the delay with perijove 9?

On Oct. 24, NASA's Twitter account for Juno noted:
Because this flyby occurs during solar conjunction we may not get confirmation of success until a week or so after the event.
And then on Oct. 31:
Hurrah! Telemetry from today's 1st post-solar conjunction passes confirm a successful flyby. Data will be coming down over the next week.

Aha! Thanks, Robert. I have checked back and I see that I was looking at the date for Jupiter at conjunction in 2016. However, as you correctly indicate, in 2017 Jupiter was at conjunction just before perijove 9, hence the delay in new images.
