Rev 210 Cloud monitoring and estuary glint (hopefully) Options

[titanicrivers]

Rev 210 http://www.ciclops.org/view/7959/Rev210?js=1 is in progress. Cloud monitoring images are now being done and one photo from Nov 26th is presented along with Celestia http://www.shatters.net/celestia/download.html grid and Solar System Simulation (SSS) http://space.jpl.nasa.gov/ images. These suffer from no details of the northern latitudes of Titan (above 50 degree N-latitude or so) and so the N polar seas such as Punga (P) are not shown. It could be I am not using the most recent versions of these otherwise great programs. The equatorial regions of Titan are well detailed however and one can use Celestia and SSS to identify the location of structures such as the Minerva (M) and Ksa (K) craters.

A couple of experimental 'golden' Titans, from the 26nd and 30th of November, using the CB3, MT1, and MT3 filtered images in both instances.

Two views of Titan on 30 November: stack cb3 on the left; red, grn, bl and uv on the right (unfortunately red was 512x512)

The T107 Titan flyby is less than 24 hrs away! Read the mission description here http://saturn.jpl.nasa.gov/mission/flybys/titan20141210/ .
A distant view of Titan on Dec4th shows sprawling Kraken in the north in the CL1 CB3 filtered image (initial part of the animation) and the colorful atmosphere in the RGB latter part of the image. Images courtesy Cassini Mission raw images http://saturn.jpl.nasa.gov/photos/raw/index.cfm
Welcome to the Titan blog Eli! Not sure how accurate it is but when it comes to the 512 red filtered images I usually change the image size to 1024 in photoshop elements so it’s the same size as the green and blue filtered images.
A ‘golden globe’ award for your CB3 MT1 MT3 filtered images Ian!

Fantastic raw images from the Rev 210 T107 approach and flyby http://saturn.jpl.nasa.gov/photos/raw/inde...storedQ=2685855 are positioned on the ISS map http://www.ciclops.org//view_media.php?id=39721&js=1 below. Some interesting areas are identified with their official IAU http://planetarynames.wr.usgs.gov/SearchResults?target=TITAN names.

Question???
Some linear dark streaks appear in Titan’s upper atmospheric haze layers. What are these?
1) Artifacts in the WAC camera or the CL1 VIO filter
2) Upper haze layer tracks made by Cassini’s close encounter
3) Saturn ring shadows on Titan’s upper atmosphere
4) Titan atmospheric changes now that the northern pole is ‘warming’ up
5) Other things the experts will be telling me about?

How about cloud shadows? These should be long like this when we are near the terminator, analogous to "sun rays" or "crepuscular rays" we see on Earth. They look a bit off center though.

Swirls and contours at the edge of the north polar hood, I'd say. Localized differences in thickness of the high altitude haze will affect brightness in shorter wavelength filters as that haze is bluish. See this enhanced view of the north pole a year ago from another angle. If you look at this equatorial view from 2 yrs ago, it looks like shadowing is playing a major effect.

The northern polar hood is starting to get more and more structure at very short wavelengths

Thanks everyone! Hadn’t noticed the CB3 image at 115K km (raw image W00090684) from which one can teased out some of the seas and hence ID the north pole. With that the bands become more obvious as part of the N polar hood in the RGB image, as discussed above.

Slightly enhanced saturation to bring out more of the orange colour in the bottom of the image.
