March has started very well indeed with a clear morning a heavy dew and good seeing. Two unavoidable situations may well delay the processing of the 172gb of data. The first is the disappearance on holiday of our local IT expert meaning although I am retired a stream of customers have arrived at my door (shame on you Anthony !) The second is the imminent arrival of severe weather meaning the delayed repair of my standby generator will have to be completed asap. However when those clouds which now cover the complete northern horizon arrive Ifll have plenty of time on my hands for all tasks. Ifll start with the quick ones being all the IR images.

Hi all,

Here is an image from Feb 9th. Average seeing. The STB outbreak is headed off at left.

Hi Jim,

 Thanks for your interesting comments and my apologies for the delay in response.

My first thoughts were that the dark markings in Hellas were related to topographical features, so it is interesting to read your interpretation.

 I am afraid that I have had to go to my family in Durban , as my dad is in a critical condition ( he is 92 years old), so I am not sure how long I will be away. Weather has been consistently overcast, but I hope to be back in action when I eventually get home.

 

Best Regards, Clyde

Hi Clyde,

Please see 3 of your recent images along with two images from the 2016-2017 apparition all with an Ls of about 128 in the attachment.  The sharp images from Go and Wesley clearly show a gray-colored CO2 seasonal ice cap in mid-winter. The maximum extent of the CO2 cap has been stated in a professional paper to bisect Hellas. The 2016 images show the edge of the ice cap to be near the Southern rim of Hellas. This may indicate that the ice cap at Ls ~128 has already been sublimating. Sublimation produces high winds from where the sublimation is present. From the 2016  images we could have predicted seeing dust clouds in Clyde's images of Hellas at Ls 128. Clyde's 20180206 and 20180209 images show airborne dust waves in Hellas. There aren't dust clouds in his 0216 image. Maybe the topography is reducing wind velocity. Note, I suspect the blue-colored H2O ice fog in the 0206 image is hiding the CO2 cap.

 


 

Well Clyde, you have awakened me from my Martian slumber. I want to add the composite image of Mars to a new Observers page but the ALPO database is being "upgraded" and is unavailable. I hope everything has been backed up. Keep sending us images. Based on other later 2016 images, I may make some dust cloud forecasts.

Hi all,

Here is an image from Feb 8th. Poor seeing this session.

The GRS is headed off while the following end of the STD is well seen.

Fantastic, Damian!
Interesting that Hyblaeus appears to be split into three parallel dark streaks. Also, the dark spot just north of the tip of Syrtis Major looks like either Nili Sinus or Antigones Fretum, I think. It hasn't been so dark in recent apparitions, has it??

Hi all,

Good seeing for this session. Excellent resolution on the surface considering D=6.2".

Hellas and Elysium clouds are prominent. Syrtis Major shows interesting structure.

Hi all,

Mars this morning with bright cloud over Olympus Mons and the other Tharsis volcanos.

The small NPC appears to be flanked by Olympia Planitia(right?) and an additional cloud(left?).

Best regards, Clyde

¤····Subject: Polarisation

Received: 17 February 2018 at 20:08 JST

 

I am fortunate to have a second scope that I can use for other purposes other than planetary imaging and at the moment I am using it for polarisation. As with all my amateur astronomy endeavours much trial and error is required, numerous gifted professional and amateur friends meant progress is being made. In 2017 I had some success but the technique required moving from the computer to the 20h scope then up a ladder to rotate the filter and then back to the pc a rushed and sometimes dangerous pursuit. As the 14h SCT was not being used  I decided an extension to the control room would allow me to use both scopes at the same time in comfort. The new setup uses a seven position filter wheel with identical polarisation filters each aligned against a known source and marked at the null position. These are then installed at six different angles allowing a 180 rotation. Phil Masding has been most generous with his time to process these with MATLAB producing a full set of corrected images which Ifm sure you will find interesting. I would also like to thank Dr Andrew Fearnside for the terminator pole schematic . Not forgetting my neighbour and close friend Anthony Wesley  who is always available to guide me when I try something new and prevent me making a total arse of myself. A collection of papers and helpful docs can be found here and naturally they are covered by their respective copyright. Feel free to browse the polarisation section and I trust this may encourage others to try this interesting aspect of planetary imaging.

Hello all,
Finally had some decent seeing for a short while before dawn.

Attached is an image of Mars from the 16th February UT.

Quite a bit of cloud visible in the blue image.

Bet wishes

Hi all,

Here are some images from Feb 13th. A very nice view of the following end of the south tropical disturbance in the first image while Oval BA and the STB outbreak are well seen in the second. Europa in transit during the session.

Hi all,

Mars this morning. Cloud is evident over Elysium and also Olympus Mons, which is on the evening terminator. The subtle albedo features around Elysium(Propontis, Phlegra, Trivium Charontis and Cerberus) are noticeable.

I suspect that the crater Milankovic may just be detectable in the R image, although not confirmed.

Cloud is visible on the southern limb. I am not sure if this is cloud that has been blown from the Hellas Basin, or whether this is an indication of the formation of the South Polar Hood. Any comments welcome.

Best regards, Clyde
