A fascinating presentation by Roe and Brown on a April 2008 storm exploding over the tropics of Titan and followed for a month using the Gemini North telescope with adaptive optics.

The press release image above is Figure 2 in the Nature article.

From the full caption in the Nature article, the degree number in parantheses is the sub-Earth Titan longitude in degrees W.
The green box in the images is centered at the location of the original April 14 cloudburst (ca. -15S, 250W).

For reference, the midpoint of the southern edge of Belet is at about [-15S, 240W].

Wow! With the Solar System Simulator I was off by 160+ degrees with respect to the face of Titan seen from earth on 4/14/08. Is this a known inaccuracy of the simulator or did I goof up somewhere?

"Wow! With the Solar System Simulator I was off by 160+ degrees with respect to the face of Titan seen from earth on 4/14/08. Is this a known inaccuracy of the simulator or did I goof up somewhere?"

I have done some investigating and it appears the Solar System Simulator (SSS) ver 4.0 has a little bug in that its depictions of the Saturn-facing and anti-Saturn hemishperes are the opposite of all Titan imaging designations. Otherwise the SSS works beautifully. I have emailed David Seal to see if this had been noted and whether there is a newer version with a fix. The graphic below shows what I found: On top is SSS versus ISS image of Titan on 8/13/09 and although the illuminated phase is similar the SSS shows the opposite hemisphere from ISS image. On bottom is the SSS view of 'Titan from Saturn' (i.e. the Saturn-facing hemisphere) and it turns up the anti-Saturn hemisphere instead!
