I try to avoid linking to my own blog (figuring that if you guys think something's worthwhile you'll post a link, else not!), but in doing so today it's only to point you all to some amazing detective work done by another UMSFer, Ted Stryk:

Wow.
Real proud of Ted. What a great group to be part of. I'm not worthy. |

Jeez... that's truly amazing work, Ted. I know how modest you are about your image processing work, so any recognition and praise you get for this find will be well deserved.

The color is rather tortured...the very left most part is simply based on the rest of the image, soon after the first moon image it becomes Orange-Blue with a tweaked "Green" fudged from an average of the two available images, then Orange-Blue-Violet with Blue tweaked to be more like Green, and, finally, just beyond the second "shadow", it becomes Orange-Green-Violet. In addition to try to force the non OGV portions of the image to behave like the OGV section, the transitions are done gradually over about 25 pixels in order to prevent discontinuities.

Awesome and congratulations!!
Very well done! Shows how a thorough search can pull new information out of old data! -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

Here is a single shot of the transit with consistent OGV color (except for lining up moon and shadow color, which had to of course be done).

That is astounding stuff. Makes me think about what else might be lurking in the PDS awaiting future discovery...

This discovery should hence forth be known as the "TedStryk Transit"

Wow...all I can do is likewise, Ted. Amazing work!
Emily's title for her article is extremely apropos..."amateur" definitely needs to be in quotes! -------------------- Yet as we leave, as we continue the often humbling maturation process of learning, it is wise to remember that we also have much to unlearn.

QUOTE (SFJCody @ Aug 6 2009, 12:26 AM)  That is astounding stuff. Makes me think about what else might be lurking in the PDS awaiting future discovery... So much, so much. I have had this one up my sleeve for quite a while, and I have a few more things in the pipeline (none on this scale though). Given that these were much-studied images, who knows what might be lurking in other shots. I think Voyager and other old data are hiding many things under their reseau paterns and gunky vidicon noise. Modern missions no doubt hide things via the pure volume of data they return. -------------------- |

 That must have come from EGD. (nope, Doug) |
