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:

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).

JIRAM M-band composites from two of the sequences. JIRAM stared at Io for several hours during PJ51 so the difference in geometry makes it hard to make a single composite so I'm processing these one sequence at a time. I'm also only going to bother with the 2 ms data, not the 4 ms stuff. Yes, the 4 ms data has better SNR but I can avoid much of the smear with the 2 ms stuff and I have to constrain what I'm working on somehow. Any mismatches you see are due to the fact that I started using my crude (but reasonably well controlled) Io control network with this data set and the background map is still the USGS basemap.



I see past me's comment about serial numbers and this will likely lead me to edit the RDR labels during ingestion on my end so that I can still use my control point network on them because there is NO WAY I am redo'ing all this work...
