On March 16, ISS imaged Titan at a distance of 1.93 million kilometers (1.2 million miles). Titan was at high phase angles, allowing for monitoring of the satellite's atmospheric haze layers. The graphic below shows several of the NAC images showing near surface (CB3 CL1) and high (UV1 CL2) atmospheric haze layers. Also highlighted is the approximately 40 deg N haze layer 'gap' or 'notch' discussed in the T 65 and T 66 topics. Images are rotated so North is at top and mapped to both SSS and Celestia grid views of Titan on March 16.

WoW, sensational color image ugordon! The detail in the haze layer is nicely enhanced.

Raw images continue to come in from cloud monitoring sequences. There does appear to be a small cloud bank at -48 to -50 S latitude on the 3/22/10 image shown below.

Composite of images N00152530 from the 22nd and N00152550 from the 24th of March taken with CL1 CB3 filters show evolution of the small southern cloud. Images rotated so north is at top. Relative size of Titan and position of terminator as seen by Cassini has been maintained.

Where is it in the 3/24/2010 image? Did it go away?

Thats a good question Mike! I could not find the cloud in the Mar 24 image either. I might speculate that the 3/22 cloud band was not very robust or was dissipating and with the 2 day hiatus simply dissipated completely over that time. I believe S-hemispheric clouds have been predicted to become less prominent with time in this season and perhaps don't persist for very long. Also as reported by Porco, C. C. et al., Imaging of Titan from the Cassini spacecraft. Nature 434, 159-168 (2005), http://www.nature.com/nature/journal/v434/...ature03436.html , the tracking of cloud motions in mid-southern latitudes consistently yields eastward winds with speeds as high as 34 m/s "providing the first direct evidence of super-rotation in Titan's troposphere" and so rapid W to E cloud movement and the spacecraft motion may have put the cloud in the dark beyond the terminator of the 3/24 image.

Monitoring for clouds over the March 22-25 period. I couldn't pull out any clouds on that last day's image either. Perhaps others have?
