PJ53 Image Collection. Exaggerated color/contrast.

[Bjorn Jonsson]

A montage of 15 images of Io, i.e. images 113 to 127. The images are enlarged by a factor of 3 relative to the original data. North is up in all of the images.



Computer generated images with a latitude/longitude grid are also included. They are based on a Voyager/Galileo map of Io.

Interesting those features in the upper left portion of Brian's map seem to show mountain shadows when compared to the white features in a prior map (section shown below). A new one can be seen in the upper left corner of Brian's map very close to the pole.

Here is a flip view between my map and the corresponding area of the USGS Io map.
(Note, I didn't attempt to align my map with the USGS map.)


Jason already noticed the change in the Volund area in PJ51. https://www.jpl.nasa.gov/images/pia25964-io-over-the-years

Nice to see the blinking animation. The associated feature name I've seen is Vivasvant Patera as per this map. I've yet to see any "Montes" type feature names in this area. The names in the map are distorted on the cylindrical projection so that they look good when projected on a sphere.

As far as names go, stay tuned (particularly the ones in the triangle shaped bright area west of Dazhbog).

Yes, there are several mountains in the north polar region. some were previously known, but the new data does give us a better idea on the shape. Since PJ55 is basically a carbon copy of PJ53 but closer we should get a better handle of the shapes of these mountains this weekend. What we don't have a good handle on are the paterae, not a surprise given they're shallower than the mountains are tall so shadows are harder to spot (though not impossible, as Michabo and Thomagata were visible near the limb on PJ53).

My apologies. I got distracted by the changing feature on the right, just below center of the flip view crop, and forgot you were interested in the mountains in the upper left.

I can see that both of these corners are pretty interesting to check out!

PJ55 will definitely be a closer up of PJ53 so seeing these changed areas in further detail will be intriguing.
