This time Mars at 47° altitude in the south east and the seeing is poor, I was able to view and sketch planet Mars but the view this time was challenging in the gusty wind. The bright south polar cap was easily visible. Hellas and Syrtis Major were the most prominent features seen and Mars has moved into Pisces since my last sketch ten days ago.

 

Sketching Materials and Equipment:

 

Location: Mesa, Az.
Mars: CM 264°
Diameter 11.24”
V. mag. -0.5
Illumination 84.4%

Date and Time: June 28, 2020: 11:25 UT
Sketch using assorted graphite and color pencils, blending stumps, White Pearl eraser on white copy paper dark background made using Gimp 2.8
Seeing: Antoniadi : IV
Transparency:  Average 4/5 clear, breezy
Temperature: 25ᵒ C (77ᵒ F)
No filters used
Scope Used: 16” f/4.41 Dobsonian on an equatorial platform 7mm, eyepiece (256x).

Nice work, Frank.  smile.gif   Mars is still very small for us visual observers so less than perfect seeing makes for a challenging observing session--glad you persevered.  You've captured all the major features visible right now at this CM, including the eroding SPC.  Well done!  It's a hard squint right now but it will get better.  laugh.gif

Michael,

 

Thank you. I am sure many good Mars observing nights are ahead of us.

I still enjoy it even with poor seeing.

Thank you both for your kind responses. I am looking forward to more opportunities to observe and sketch the red planet.

Frank,

I meant to ask you--did the Sahara dust plume affect your observation?  You captured so much detail in your sketch that it didn't occur to me that you might have been looking through dust.

Hi Michael,

 

Not seeing any of the Sahara dust as of today but it is above Mexico and our winds out of the south east could bring it in.

 

Frank :)
