D. A. Peach. Loudwater, Buckinghamshire, UK.
14" (35cm) Celestron SCT @ f/39.5.
Lumenera LU075M CCD camera.
Seeing fair to poor (Pickering 5-3.)
Transparency fair (2.0-3.0mag) mist/haze/sctt low clouds.
Wind SE (5-10mph.) Heavy dew.
Alt= 50-55 degs.
Here are some images from last night. Fair to poor seeing.
Some interesting detail in Blue light. A clumpy evening cloud is present over
Libya/Southern Syrtis Major. Hellas is free of mist. The NPH is again thick
extending over Acidalium. Note the detail around the SPC in red.

Mars this morning under not so steady skies, temps dropping 42 degrees
overnight. Some small blue-white patches of cloud or fog noted in the
Chryse/Lunae Palus region; the North Polar Hood has anything but retreated
in this longitudinal expanse, encroaching far southward into the Zanthe area.

Here are images of Mars taken October 18th 2005 from Houston Texas.
The dust cloud has moved south quite a bit since yesterday and several
core concentrations are visible in Eos.

68.7F, Relative Humidity 69%, Red/Grn/Blu @ 80% scale.

My image taken on 10/19/2005 shows the dust activity in the same general
area as images posted recently on www.skyandtelescope.com . The storm
obscures much of Aurorae Sinus, near Mare Erythraeum. I would appreciate
confirmation of dust activity on my image from other observers. I am still
processing images taken 24 hours later as we speak, and will send them as
soon as they are ready. Good observing to all!

The main thrust of the cloud continues to move north has and moved into
Valles Marineris.

The dust Storm has changed, It is now an irregular serpentine streak.

Very notable and curious changes in the dust "event" in Chryse in just the
past 24 hours; note that the characteristic "V" shape of Oct. 18 has totally
given way for a more linear, streak-like feature which is somewhat less
pronounced. A comparison image between these two dates is in preparation
showing the remarkable transformation of this feature....will post shortly.

Showing the 24-hour change in the Chryse Dust cloud between Oct. 18 and 19,
centered on CM 50; very interesting comparison showing incredibly rapid
morphological change and area coverage.
