MARS 4TH FEBRUARY 2010
Mars continues to impress us with a good show. Last evening offered good seeing but which slightly deteriorated some 5 hours later.
Using Wratten #21 filter, Syrtis Major was very distinct and its patchy albedo variation was very well evident. Syrtis Minor was slightly evident.
The good seeing also permitted the detection of Hesperia which divides M. Tyrrhenum from M. Cimmerium.
The blue filter # 38A showed lighter patches along the limbs and central portion, which could be indicative of clouds and hazes corresponding to the lighter blue regions.
