Perijove 51 is next Tuesday (Monday evening here in Tucson). I've published a new video about the Io encounter during this pass along with a review of the JunoCAM images from the last one back on March 1:

https://youtu.be/6oMDd7rAeHw

The biggest takeaway is that this is a VERY long encounter. Just as an example, during PJ49, Io was only covered at least in part by the JIRAM field of view for 6 minutes. During PJ51 it will be in the JIRAM field of view of more than 7 glorious hours. Io will also be in the JunoCAM field of view for more than 48 hours, though obviously Io will be too small for most of that time, but still! Definitely looking forward to this encounter next week. I'm on travel during the encounter, but I'll be back home the time any JunoCAM data arrives (I presume that because we're only a month post conjunction that we can expect a bit of a delay, but that's perfectly fine).

Nice video, Jason. Sorry to disappoint, but Junocam is only taking 10 images of Io this time, from about 02:30 to 03:45. They are all lossless.

I suspect that Prometheus will be a bit too far from the terminator in the first image, but one can always hope. But Io should be in some of the Jupiter images…

Raw images are up on missionjuno.

Maybe a plume in JNCE_2023136_51C00069_V01-raw? Not many pixels, but it seems like it could be one.

Might be the mountains around Gauwa Patera.

There MAY be a plume in JNCE_2023136_51C00065_V01. I'll need to check the location...

No, I'm not so sure about it... too far west to be Prometheus....

One image down, eight more to go.

Finally some absolute, no doubt about it surface changes around Volund. The northwestern distal flows are much darker and there is a new patch of dark material on the west side of Volund. This matches what we've seen with JIRAM in the last few flybys.

There are some spots visible in the dark side of the image on the left; are these glowing lava flows, or hot pixels?

The raw images have many pixels. However, as pretty much all of the terrain was imaged >2 times, it should be possible to rule out which if any correspond to anything physically real.

Strip of three images (63, 64, and 66). Sorry for the terse description. It’s getting late here… and I really could use some sleep…

I will make a quick note that if you see any random green spots, that’s noise. Red spots, now those are things I need to check, but in the morning.

Yeah, there does appear to be something going on just east/right of the terminator in JNCE_2023136_51C00069_V01. Bright spot appeared in all three color channels reducing the likelyhood that it's the result of a hot pixel or particle hit.

yeah, that's definitely one of the mountains around Gauwa Patera at 40N, 5W.

That then makes me wonder if it's simply that a peak is poking up into the sunlight from beyond the day/night terminator.

Okay, I'm a bit more convinced that the plume in image #65 (the over exposed one) is real. It shows up in two filters. There are no known mountains. It's too tall to be a mountain. The limb location of 11S, 165W is consistent with Culann, an occasional plume site from Galileo.
