Looking at these picture just strengthens the need for more science from a orbiter.

Here is the Titania sequence. The color is based on the OGV set. The problem with the full phase sets is that although Titania is rotating, the images are boresighted on the south pole, so it is simply going around like a pinwheel.
Also, here is a full view from a stacking of all five "pinwheel sets" with OGV color. -------------------- |

Here is a slightly better full image.

There's an interesting new paper in the January 2006 issue of Solar System Research:
Mutual occultations and eclipses of the major Uranian satellites in 2006–2010 N. V. Emels’yanov Solar System Research 40, 79-83 (2006). DOI: 10.1134/S0038094606010047 Abstract |

This nice image from Ted, in concert with the others previously used, has allowed me to increase the areal coverage and the use of color in my Titania map. The latest version is at this URL: http://laps.noaa.gov/albers/sos/sos.html#TITANIA -------------------- Steve [ my home page and planetary maps page ]

Emels’yanov Solar System Research 40, 79-83 (2006). DOI: 10.1134/S0038094606010047 Abstract Yes, some eclipses actually started in 2005, opening a season which hadn't last visited us since the 1960s... I proposed (on a very low level, over a breakfast table) a project to photograph the first eclipse, which was visible from only a sliver of the Earth's surface that included an observatory I had access to, but nothing came of this, and it was probably cloudy anyway... |

Nice images Ted. I went ahead and updated my cylindrical Ariel map with the two largest of these. I believe I also figured out the location of the night side image you sent me a while back so that is included as well.

I may tinker to try to make the extension of the canyon system into the north more obvious. Also, I will dig for more distant observations to fill in that nasty gore in the southern hemisphere. -------------------- |

Steve, I think the image in post 5 of this thread might be a little clearer than the one you used. And these two (almost the same as each other) fill in the gap.
I'm especially pleased to see the nightside detail added to your map - certainly a first in the history of planetary cartography (for Ariel, I mean). Phil It's very hard to get a good image out of the dark side views. Ted has done a great job. I tackled it as well, with this as one version of my efforts: It could extend that dark side coverage, including the apparent extension of the canyon area. If only the Voyager imaging team had recognized this possibility at the time and planned for it! We could have had good images of another 20% or more of several of these moons. Phil -------------------- ... because the Solar System ain't gonna map itself.

Wow - images aplenty. Challenging to decide exactly what to try. I did add a link to Phil's Umbriel map from my website, hope that's OK. For the Ariel gap filling I tried the largest one in Ted's series from post #54. This filled some of the equatorial gap, now if I could just find one to fill the rest

There are no skipped sets, so this is pretty much what we have to work with. -------------------- |

Thanks for including all the images Ted. I now see after taking a closer look that the third image from the right (post 54) fills in the rest of the gap. So I think we now have the entire equatorial region covered.

Is there a similar set of images for Miranda?
