Hey,

 

I observed the Red Planet yesterday morning after sketching Jupiter and before sketching Comet NEOWISE.  I had a doctor appointment yesterday too, so I'm not quite caught up on my sleep deficit.  lol.gif 

 

Mare Sirenum was showing pretty dark but Solis Lacus was ill-defined.  I think the dust storm of 2018 has changed the albedo somewhat.  We'll see when it rotates more to face us (and Mars gets bigger).

 

The sketch was started at the eyepiece and finished after I came inside.  I used 2B and HB pencils, a stump, and color pencil dust applied with a Q-tip on Strathmore drawing paper.

 

Mars is up to 12 arcseconds of apparent diameter!  cool.gif

Michael,

 

Beautifully done. Mars is growing nicely in size. It is about the size it was the last sketch I made in November of 2018.

I really like your work here. This should only get better.

 

Frank :)

Thanks, Frank.  smile.gif   It's nice to know it's growing in size--that will help overcome my floaters.  grin.gif

 

I like this comparison with an image by Efrain Morales on the CMO homepage.  cool.gif

Yes it compares very well with his image.

Hi,

i had a look on Mars the last 8 and 9th and I found the atmosphere rather hazzy.

Especially at the North Pole area well whitish, also near the terminator.

The contrast level of the main features remain rather faint.

with the w80A filter, the main formations are faded indeed but also with the w11 filter. The w12 does not bring more contrast in comparison with the w11 filter.

The conclusion is an hazzy atmosphere, whitish at north, misty on the whole surface except near the polar cap.

I do not have presently some scan means so that drawings will be issued later on the jpn also website.

Good skies.

Stanislas Jean

Stan,

 

I haven't been seeing much haze--just a narrow morning limb arc and once, on 4 July, I saw a bluish haze on the northern limb.  When I used the 80A on this 7 July observation, the disk was clear (except for the limb arc.  I could see the albedo features clearly.  Maybe it started to get hazy since then.

Pse have a look at the jpn also site.

A picture of mr Naryshnyi on last 11th is well showing this hazzy status, with rather confidential status about contrasts.
This picture represents very well the visual status with good images.

Good skies.

Stan,

I looked at Y. Naryzhniy's excellent image of 11 July.  There certainly is haze present over most of the globe.  With the Martian southern hemisphere well into late spring now we'll be seeing more haze and clouds.
