Hi all, here are some images of Saturn from last night. The conditions were very good and surprisingly I've been able to image the planet with many filters. No spot is detected nonetheless, even that one first seen on september 13^th that could have been caught in the last images (RGB ToUcam).

Best regards

Hello to all

I'm sending some images from this morning - seeing was very good and all wavelengths have worked well ; even in UV a few details can be detected it seems despite the noise (like the dark SSTB spot).

Good observations.

Hello everyone : I have observed Mars tonight in a few lulls, and did manage to catch two images of the Hellas hemisphere (IR and Blue). It seems that no dust is visible there, the strange aspect of the Hellas basin may be due to low resolution only. Images made with a 355mm SCT. I will possibly have more chance to image Mars this week.

Hi all, the seeing is good tonight and I'm finally managing to use the C14 correctly. I've been able to take a full set of images from violet to infrared, and they prove well I think that no dust cloud is present in the Hellas hemisphere. Note however that the atmosphere above the south polar region looks completely clear with a sharp round area above it (especially seen in green and RGB). There is much clouds otherwise.

Subject: Dust in Deucalionis

Hi everyone : I have observed some bright orange clouds south of Sinus Sabeus tonight (I will post the images later), nothing was there yesterday evening ! The area should rapidly face the USA longitude I suppose.

Many Thanks Nicolas, your beautiful drawings depict exactly what I imaged and saw yesterday evening. Hoping it's going global...

Hi all

Here are my images from yesterday. A big yellow cloud is visible west of Hellas above Mare Serpentis. Actually it was already visible on my images from december 15th, but a bit further to the west. Tonight hopefully I will observe again to see if something happens on or near Hellas.

Hi all, here are some Saturn images taken with the C 14 of my astro club. The conditions were very good but it seems that no spot has been detected.

Hi observers : these are Jupiter images taken with a C14 under good seeing. They show the mid-SEB outbreak area. The UV image has been taken at prime focus and then resized to 150 %. Note that BA looks invisible in infrared ?

Hi all. Here are some images of the dust cloud in Noachis, observed last night under poor to fair seeing only. Hellas has been reached by the dust it seems! Interesting to note that the North polar hood looks extremely broad in every blue image, as if it was extending far to the south (but it could just be the morning mist ?)
