SPC became small, and mist became conspicuous in the morning side and
evening side. The cloud which is familiar with Nix Olympica(125W,+20)
isn't seen.A cloud can't be seen in the mountain of Tharsis(100W,+10)
as well. Blue crealing can be still seen with the blue image of
Christophe Pellier.

今月初の観測になりました。
かなり極冠が小さくなりましたね。シーイングはまだいまいちです。
早く秋の移動性高気圧が張り出して来ないですかね。
晴れると寒いです。もう観測中は５℃前後です。

Seeing slightly worse than previous night but transparancy was better.

Hello everyone
Last night I've managed to take a few images in a three hours gap in several
days of clouds and rain ! As expected, the sky was superbly transparent but
quite turbulent. However the minimum is caught : all the markings are there
so there is no dust storm, and clouds are shot. Also imaged is the yellow
tint of the morning Hellas, something that have been observed for several
monthes I think.
I have made a first try with a deep blue filter with transmission pic at 380
nm and bandpass 300-500 nm, however better conditions would be required to
make a real evaluation.
Good luck for your own observations
