Mars Sketch 7.15.03

Hi,

I had very good seeing conditions while making this Mars sketch. Additionally, Mars' image size was noticeably larger since the last time I had good conditions last July 4th.

I guess the stand-out features for me during this observation is being somewhat successful in seeing the break up in the Amazonis region. Though subtle, I tried to render the brightening I saw on the "following", sunrise side-left side in drawing. Chryse's brightness is a bit exaggerated. Also, what I believe to be Pyrhale Regio, on the sunrise limb, seemed very bright, brighter than Argyre.

Please keep in mind that the filter system I use could have played "tricks" with the apparent brightnesses mentioned.

Also, thanks to Carlos H. & Jeff B. for helping me out with being able to name some of these geographic features. I guess that I may be able to understand some of these better before this opposition is over.

Thanks,

Sol Robbins

Wow Sol, that's a great sketch, with sharp edges all over the place. Amazing details.
