Tropical clouds!

Very subtle and fragmented, but they are present in multiple images:


("brightest" cloud indicated by yellow arrow, red outline area shows general region where cloud fragments appear)
Center of area is around [-15S, 250W] S of Belet
S is at top.

[volcanopele]

About the same latitude we've seen before for these kinds of clouds, but this is the first time we've seen them this far north at this longitude band.

Here's a rotated, gridded version with approx. cloud location.

False color composition from Images taken on Jan 15, 2010:



Some subtle structure visible in S Polar zone, plus the mid-latitude gap (band? belt?) in the haze layer in both blue and UV filtered images is much more sharply defined. (Zoom inset shown).
I'll leave it to titanicrivers to figure the correct latitude

Image rotated so that N is at top.

Juramike's wish is my command. Titan and I have taken the liberty of flipping Mike's image on a vertical axis to match up with Cassini's and the SSS's view of Titan on 1/15/2010 from about 1.2 Mkm. It appears that haze thinning gap is from 30N to 40N latitude.

T65 Radar swath.
A great picture of Lake Ontario and the other smaller, but darker lake.

Enjoy.

And one more picture.

Enjoy.

And possibly a smaller, shallow lake in the right-hand section of the swath.

Great pictures Peter59! Thanks for posting these and all previous ones for us.
Below I have tried to place the T65 SAR swath across the S Polar region. (left image). The upper part of the swath went across Mezzoramia basin, a very interesting place that may have been a large lake or small sea in the past. A 'shoreline', (part of which is outlined) reinforces this conjecture. (right image). The T7 swath also shows part of the Mezzoramia basin shoreline. http://photojournal.jpl.nasa.gov/catalog/PIA03563
There is some overlap of T65 and T7 at the 'shoreline'; ? an opportunity for a topographic mapping?

[titanicrivers]

Combining T7 and T65 overlap region allows an extended view of the Mezzoramia shoreline. The image below also adds a 3D element and reduces noise (over detail) for a view from above, blurred a bit by Titan's atmosphere.

To date do we only have 1 Sar image available online?

I was looking to another from another flyby to do a blink comparison.

How about this great site http://pirlwww.lpl.arizona.edu/~perry/RADAR/ with most of the SARS (as jpegs) released to the PDS placed on the latest ISS albedo map (updated by VP just a few hours ago !!!). Might have to reconstruct Ontario L from T57 T58 and blink compare with T65.

(updated by VP just a few hours ago !!!).

Thanks for pointing that out. I'd been checking regularly but less often of late as I began to think he wasn't going to continue past T50 for some reason. So glad I was wrong. These are much appreciated, thanks Jason.

(Now for a quick dive into the new swathes to look for more cases of possible diapirism like that discovered on T64. There's a likely looking candidate about one third of the way along T55 for a start.)

Ignoring Jasons superb work - did you not look here : http://photojournal.jpl.nasa.gov/mission/C...t:Radar+Mapper:

If not, why not?
