Brian Colville catches bright section in the next of the west of Oxia
palus(8W,+13). This part often looks bright this season. Perhaps, it
seems that the fog has occurred. The appearance of NPH is understood
from the image of John Kirchhoff Hudson very well though the shape of
the bright cloud made the vicinity of Mare Acidarium (30W,-50) changed
for the worse.

A series of four images with very good detail:
Some fairly steady skies tonight and four images over nearly two hours; much detail
revealed, among which is the large north polar hood/cloud formation rotating into view
over this period; south polar cap is developing a dark "melt line" and there are some
interesting bright areas of possible yellow cloud formation.

At this location its very rare to get more then 2 or even 1 nights with good seeing.This rule was broken
now,and the fourth day gave even a longer period of exellent seeing.
Therefore I concentrated on imaging the Huygens crater,which could already be seen easily live during
capturing on the screen!The crater is visible in the image as a bullet.

CML = 243.
Seeing was fair/good and skies were clear....we only get a few of those a
year from deepest Suffolk!

Seeing was still fair/good but skies were misty with much thin
cloud.

I captured one set of filtered images this morning between 08:00 and 08:45 UT. I have only managed to process a few and have noticed a spot of interest. I have sent out the red and RGB composite with the area marked. I will not be home to work on finishing these until late tomorrow...must make a trip with my daughter to visit specialists at Sick Kids Hospital in Toronto tonight and all day tomorrow.
Details are marked on the image. The area I find of interest is along the border of Sinus Meridiani and Chryse, following the slender curve of Oxia Portus. There is a bright area in the red image, inside of the limb processing artefact. Potential cloud/dust?? This is probably of no significance, but I wanted to send it out ASAP just in case.
Please advise if there are any questions or comments. I will check e-mail tonight before leaving and again tomorrow when I return.

Very good seeing conditions this morning. The NPH is very visible and there appears to be some darkening near the pole. The darkening appears to have changed appearance slightly compared to the image of the 19th.

Here are some images from the 21st. Very good seeing before the fog arrived.
Some interesting hazes visible in G and B images. Some yellowish haze visible around Hyblaeus. Also and evening limb cloud visible over Aeolis. Hazes over Hellas and Libya again. NPH is thick but partially transparent.

The B and violet filters worked wonderfully.
There is an interesting chain of white clouds at the north-west of Syrtis Major and Mare Thyrrenum. It looks to form at or near the famous south-north slope from old terrains to more recent ones at this point. Evening mist is quite prominent.
