Among the large craters of the lunar southern highlands, a nearly 4 billion year old crater stood out over the terminator on this evening just after local sunset here in the central USA. This crater is the 230 km. diameter impactor known by the name Clavius.  Clavius is blanketed with a sizable number of craters and numerous craterlets . The north-northeastern rim of Clavius has a large crater resting upon it and most of its rim is just catching the light of sunrise. This 52 km. diameter crater is Porter. Much of the central floor of crater Clavius remains in darkness except for Clavius D (21 km.) and to its right in the sketch Clavius C (13 km.). Note that crater D is casting a nice shadow across the high central floor which is just beginning to light up in the lunar morning sun.

Nice Frank! This is an interesting view of this crater.  

Your sketch looks like a real sculpture.

Fine sketch! Clavius is always an impressive crater to sketch.

I made an almost similar sketch some 3 years ago. I turned it to the same orientatie as your sketch.

Jef,

 

How about that. The sketches are very much alike.

So it caught your eye too 3 years back.

An excellent observation observation of the crater Clavius on the terminator. You have captured the crater rims and shadows very nicely. Thank you for sharing it with us all.

 

Jef - An excellent observation of Clavius on the terminator as well. Thank you for sharing it with us all.

Very nice Clavius sketch Frank.

 

I also think its great when people add sketches for comparison to threads like this, I've admired both yours and Jef's lunar sketches.

[frank5817]

Uwe and Mike, Thank you both. Yes, I was glad Jef posted his sketch too. Frank

Frank and Jef, very nice sketches. I did last year this quick drawing:

It was fascinating to watch the sunrise and quick changes in the crater interior.

Frank, I bet it was too striking to pass up. You captured it well, as usual. Nice to see your still going at it.

Sasa and Norme,

 

Thank you both.

Sasa- It is always a thrill to watch the sun hit these high points on the Moon as it rises.

Ed,

 

Thank you. This has been a lean year so far for sketching, so I'm trying to catch up before it gets too cold.
