East and West noted in the sketch are Martian E/W, not celestial E/W.

Observation Notes:
I hadn't observed Mars for a couple months when I finally gave it a last look for the 2005 apparition. The seeing was on and off crud to semi-crud. Mars was a beautiful, salmon color. Gradually, some darker features began to emerge. The smaller angular size of the planet and the seeing problems made everything very difficult. It was still a great sight to behold. There was a very bright haze northwest of Mare Chronium. The North Polar Hood had a blueish tint, and more limb haze crowded the east limb.
