Hi observers : last night I have seen the quality of the seeing passing from very poor to fair or even fairly good in just a matter of minutes :-o. I think however that because of my fear of the clouds I have adopted incorrect parameters for the RGB images which are too noisy. The morning haze is very bright, however.

Hi everyone, the seeing last night was again very variable and in one hour of time passed from very poor to good ! Unfortunately there was also a haze that has considerably lowered the contrast of the images.

Hi all, here are what could remain as my best images of Mars. Again, last night the seeing evolved from very poor to good very rapidly around 0 H UT, and this time no haze was around ;-) The evening mist to the east of Syrtis Major is quite prominent.


Best wishes,

Thanks Clay. I have also remarked how fast the SPC has shrunk in only two or three weeks ! And now in the following longitudes it's almost invisible, due to the non-centered cap over the pole...

Subject: Saturn images on august 31, 2003


Hi observers, as I had good seeing on Mars two nights ago, I have waited to make my first images of Saturn of the new season. I have used the two webcams (colour and b&w), but the planet is still dim and I could not use much filters. Even the IRcut was too much for the colour Toucam. Maybe the images are too heavy to be passed on the Saturn-ALPO group ? Best wishes,


PS : some of you may want to receive only Mars images from me, please feel free to tell, if so.

Hi all : for these the seeing was fair.


Steady skies
