Here is my preliminary images from this morning. I have three other sets to
process, but are from an earlier time. This set shows the dust disturbance
best as it is the last set taken for the morning. I wanted to keep going,
but the ole body said 20 hours was enough!
The dust is strong in green light and is showing on the RGB with a slight
greenish twinge to it. I doubt this is normal, but a result of processing. It
does show up easily though because of this.
Dust activity has quieted down from the day before, but still strongly visible
and appears to be terrain following. The activity is barely or not visible at
all in blue, indicating the dust did not make it into the upper atmosphere.
The dust remnant form last weeks activity is still visible to the South, but
is breaking up and dissipating. It is still visible in blue so may take a
while to totally disappear.

Showing a somewhat weakening yellow dust disturbance that was prominent
between Sinus Meridiani and Margaritifer Sinus. High contrast inset image
(lower right) demonstrates the true nature of the bright core cloud. Image
in moments of very good seeing. Note the very bright blue clouds within the
northern polar regions as well as the odd diagonal darkening wave that persists.

Composite of three dates centered at near Martian Longitude 350 deg.,
demonstrating the pre-, maximum-, and current distribution and outbreak of
the remarkable dust event of October 28. Dates are Oct. 27, 28, and 29;
from the latter image note that the intensity and concentration of this feature
has subsided and distribution of the dust appears to be commencing, leading
it seems to less density and concentration than during the Oct. 28 sudden
intensification of this area.

There is another outburst on Mars. It has encroached onto Sinus Meridiani.
Here is a Red image hot off the press along with a comparison image from
the 29th of October.

Images of Mars in the Cousins I band and a color image made from
BVI filter images. Obtained with the Michigan State University
60-cm telescope diaphragmed to 20 cm to prevent overexposure on the
Apogee Ap47p CCD. Seeing 4-5/10.
Clouds rolled in before "the view" rotated into good position this morning,
but some evidence of the Sinus Meridiani event is evident on the limb.
Poor and variable pre-frontal seeing conditions persisted.

Attached are my observations from last night/this morning. My images show
the same "brick reddish" patch southeast of the advancing dust storm that
David Moore reported.
