UPDATED Oct 21 - (please see last picture)
NEW four-day sequence presented below, as well as accompanying animation from those images.  NOTE that each of these images presents actually the SAME face of Mars, so the changes have been quite dramatic!
---------------------------
A cloudy day on Mars to say the least; I was able to obtain images that shows very
distinct coloration differences on major cloud activity on the Red Planet.  A very
interesting view.

The yellow dust storm seen on the CM has morphed greatly since Oct. 18 to 21 and now has
spread its way southward as can be easily noted in the full color and green images.  In
addition to this rapidly changing feature, note the very bright concentration (seen best
on the terminator) just preceding Mare Sirenum (far left on terminator).  Also there is a
remarkably bright blue concentration seen clearly very near the northern pole that is
likely associated with the thick northern polar haze seen through this longitudinal span.

More high blue clouds are suspected on the right limb, over the area of Solis Lacus, not
seen in full view this morning because of approaching earth clouds.
----------end update for October 21

Oct. 18:  Attached is an image of Mars showing the newly developed "V-shaped"
dust storm in CHRYSE, centered near Martian Central Meridian 57 degrees.  The
feature has greatly developed overnight into a large and bright cloud and likely will be
spreading quickly in the next few days.  It appears that the cloud is sheared or separated
by regional topography to the south.

The bright yellow cloud, very likely to be much larger in coming days and spreading southward, is clearly visible in average telescopes visually without any additional aids necessary.
