Summary:

October began with a great increase in disk diameter to maximum of 20.2”, many orographic and frost clouds were seen, particularly in the Tharsis volcanic province, the North polar Hood remained large and very blue at times with brilliant white spots appearing from time to time. This month began notable dust activity just past mid-month with two storms appearing in the Chryse region, with the 2nd expanding northward. This storm continues to expand through the Eos-Coprates canyon complexes, covering Solis lacus and moving westward into Argyre I and beginning to extend south towards Meridiani. Sharp detail of Sabeus Sinus and some of the best ever views of this region were obtained after Oct 20th. Pandorae Fretum appears excessively dark this time, much darker than in 2003.

Oct 25th…dust appears to be moving over Mare Australe and funneling down in to the Hellas basin, Hellespontus Montes appears sharper and delineated against the dusty background, dust also moving into Margaritifer Sinus and renewed activity in Chryse.

Oct 31st… Mars remains dusty with renewed activity in Sinus Meridiani, contrast very good at times with Mare Tyrrhenum and Syrtis Major appearing a greenish color. Great views even in less than ideal seeing during closest approach, Oct 28 through 30th.
