Dust storm near Hellespontus(335W,-50) isn't changing just as it is.
This is doing a way of that it is possible to see with the the
same of 3 days. Therefore, this has the possibility of the change
which was caused to the pattern of Mars. SPC is mainly sublimated
at the longitude near Mare Cimmerium(220W,-20). Eric Ng recorded
the change that Hellas(290W,-50) became bright.

Hi all : this morning the seeing went from poor to fair but the webcam
finally handled this correctly when the planet was high enough.
Masatsugu : I have followed your advices and tried to get better G and B
images. Apart from the two RVB series I made three minutes avi files
(instead of 1-2 generally) for the 03 H 27 green image and the 03 H 35 blue
image, in order to seriously increase the s/n ratio. The blue filter for the
last one was tilted following Okano's idea, it seems that the dark markings
are erased a bit more but this is not evident. I don't really know if these
two last shots show the evening mist, maybe over Argyre, but I don't really
see the presence of the morning mist.
Best wishes
