Sky was clear on this night and the eleven day old waxing gibbous Moon was high in the sky.
The atmosphere was calmer than predicted so I decided to sketch. On this occasion I decided to move away from the terminator and pick a bright ray target on the eastern side of the Moon near the limb.
Mare Crisium and crater Proclus looked like a good choice with the Sun high over them. Shadows were not visible but the bright ejecta rays were.

 

Sketching and Materials:

Date and Time: 01/06/2020; 07:10-08:15 UT
Black Paper Sketching Pad 8”x 6”, Conte’ crayons  and pencils both black and white, blending stumps, White Pearl eraser, 10” f/5.7 Dobsonian telescope on an equatorial platform 9mm eyepiece at 161x.

Hello Frank,

thanks for sharing this excellent sketch of Mare Crisium with us. It has paid off to leave the terminator!

Clear skies

Excellent sketch, Frank.

 

I always get that bit extra excited when Proclus gets eclipsed by the Earth's shadow. 

It means a Total Lunar Eclipse is about to occur - and Proclus is often the last crater to be occulted before the Moon turns red or orange. 

 

Proclus' rays are wonderfully portrayed in your sketch, Frank. 

 

Please keep your sketches coming during 2020!

 

Kind regards from Aubrey.

Pedro,

 

Thanks, the sketch is not very accurate and  I drew it pretty quickly.

I wanted to draw a bright ray sketch at high sun. I actually find this more difficult than a terminator sketch with all the shadows.

Superb and sketched with another style.  

This moon target is always nice to observe.

The quick sketch gives another approach, less photographic like and more "alive".

This is a good method to use when the phenomenon change quickly, like sketching a meteor or an eclipse.

Bravo Frank

 

PS: Tonight the moon will be a little bit different because of a penumbral eclipse, anyway this is very difficult to detect clearly.

 

Michel

Michel,

 

Thank you for you kind words.

Yes with the full Moon I know about the penumbral eclipse, it will be over with before moonrise here.

The difference in brightness is mostly difficult to detect based on my past experiences.

 

Clear skies to you.

 

Frank :)
