A regional dust storm which began on November 11 in southern Chryse/Valles Marineris is now observable in the early evening from the UK. I was able to see it last night at around 17.00 UT, though it was right upon the evening limb. The storm expanded to the south over Mare Erythraeum, and fresh dust cores have formed in Chryse, but as of yesterday the bright dust clouds stretching along Valles Marineris had faded somewhat.
All observations are welcome. Please send them to me. If members just post them on their own pages I will not see them!
