Hi all!

 

Here is a drawing of Mars I made this morning.  The planet is now a reasonable size at 12.4" and very noticeable in the sky.  At present, I could only reach it with my 8" Newtonian but as seeing was around AIII-IV, this was quite sufficient.

I was quite struck by how muted the features appeared on the Martian disk. Erythraeum, Dawes Bay and other features were not particularly striking.  I had a fairly clear impression of yellow dust both on the limb and covering Solis Lacus and perhaps into Erythraeum and extending to the Argyre basin in the far south.

 

The southern polar cap was particularly brilliant,t with vague darker patch present inside.  The Lowell band was particularly dark (probably the darkest feature on the disk) and seemed to be irregular in a number of places rather than a smooth band.  To the far north, the limb was a whitish colour.

 

Best wishes,
-Paul

Agree with you Paul regarding the featuring covered by an hazzy atmosphere.

Rather misty.

Good skies.

Paul,

Nice observation and nicely rendered.  smile.gif   You show the same projection on the SPC that Dave had on his recent drawing.

Just love colored Mars drawings.  Never quite got the hang of it myself.  Mine have always been to dark B&W because the old ALPO  journal editors needed high contrast sketches to publish in the old printing methods, so I never changed.

Thanks everyone!
 

@Jeff B1: It takes time to get all of the colours for Mars correct but it is worth it I think. I find all of the planets in the solar system to contain some lovely colours!

Hi Paul. 

I used to see you on The Sky at Night with Peter Lawrence and, of course, the great Sir Patrick Moore. 

How I miss you on that show.

 

I truly adore all your sketches especially this one of Mars. .

I never knew of the Lowell band before which clearly forms at the end of the South Polar Cap. 

Thank you very much for mentioning it here.  

It just goes to show I can still learn something new every day!

 

Clear skies to you, 

 

Aubrey from Dublin.

Capen used to tell us that Mars was ochre colored. I never really found our what ochre was smile.gif  Mars appears different depending on aperture, at least for me.  I always like using my 12.5" more so that the 16" because of the image brightness in the 16" was just too much for me.  The colors in the 16" were more towards the white instead of red.  Maybe it was my eyes playing tricks on me.
