I never grow bored of Rupes Recta, in fact, when the phase is right to observe
it, there is where you will find me. I often compared it to the topographic
features of Paris, France. Outside the Paris basin it is ringed by tiers of
gentle plateaus slopes that abruptly conclude into precipitious cliff scarps.
Then well beyound, into the German border we find the massive graben in which
the Rhine River has insinuated itself within. Inspite of these comparisons, they
fall short, for the Straight Wall is a unique feature. Maybe in our lifetime the
triggering cause of its existance will be revealed.

My private nomanclature for this feature is "the Las Vegas Strip". I envisions
numerous hotels and township complexes situated parallel on the upper surface.
Tax revenues collected from these businesses would pay for on going non stop
scientific research. Wouldn't you pay for the chance to ski down certain groomed
slopes of Rupes Recta? Or being a workman on a crew that is deep drilling for
core samples or the lab tech back at the labs who will analyze them. Or perhaps
standing near the edge and looking out over the vast Mare before you with
binoculars. But this is only a dream. I guess Niagra Falls will just have to do
for now.

Outstanding, yet again Wes!

Wes, that has to be one of the most outstanding lunar images I think I've ever
seen.  You almost feel like you could open your lunar lander door and climb down
to the lunar surface!

Absolutely stunning!  Well done.

Yes Wes, I've seen those...  on the LPI site, in the Apollo image gallery.

Hi,

Another one from 11-05-09,Theophilus IMO has the most impressive central peak of
any crater on the near side in fact I think it is practically a mountain range
in it's own right.
The image details are with the image.

Now I understand, Danny.   I took those to be old, flooded craters.

Peter,
No no! The sperm-like formation east of the bright ray-crater La Condamine S
is just a wrinkle ridge (the one with the small bowl-shaped crater at its
northern end). It's those curious "handcuff" shaped arcs in that region!
They are all over! Some of them have the appearance as if they are "closed",
others are "open".
I call these handcuff shaped ring-arcs "moulures" because they have some
sort of curly "1700's" look (Bass-relief shapes which are noticeable in
antique ceiling-decoration, etc...).
P.S.:
Note also the possible concentric crater La Condamine SA, west of the bright
ray-crater La Condamine S! (yes; concentric craters abound in this region!
Perhaps they are all related to those handcuff shaped arcs?).

Danny.

feature to the right of the very bright crater near the top centre of

Danny - I am not completely sure what features you are referring to as moulures. There are a lot of intersecting and flooded basin secondary craters here that have interesting arc segments.

Dear group,

A couple of months ago (or perhaps more) I noticed a curious kind of lunar surface formation on several of Lunar Orbiter 4's photographs. This formation looks like some sort of "twisted arc" or "twisted ring-crater", and could be seen as a lunar equivalent of something which is known on earth as "moulures" (I hope I use the exact word for it)(I mean: certain Bass-relief "things" that one could see while observing historic white-painted ceilings, in a museum for example).

I have included the link to one of those L.O.-4 photographs, which shows La Condamine and the field of twisted arc-shapes north of it (in Mare Frigoris).

Now, how would we call this kind of surface formation? ("moulures" is rather clumsy, it needs something much more scientific).

Was this kind of surface formation already investigated and described somewhere?

Another curiosity is the abundance of Concentric Craters at regions of "twisted arc-shapes".

The quarters refer to the lunar cycle - new, first quarter, full, third
quarter, and back to new. Think of it as quarters of the orbit if you
like. So, yes, full moon is second quarter. So at first and third

Woke up early and saw this moon halo through the bedroom skylight.

(Seems strange to talk about imaging the moon at such a short focal length :) That's Mars just above the moon.

I wonder what you mean by "early", Bob.

I woke at 0400 and saw a clear, beautiful, third-quarter Moon high in
the sky, so I dressed hurriedly and opened up my observatory, set up my
camera and took a trial shot of Clavius. I was then prowling the Moon
looking for more good targets when I realised something was wrong. The
Moon was vanishing into the mist...

Well I'm glad someone got something better out of the morning <grin>.
Nicely caught. I admit I didn't notice if there was one here. Nor did
I realise Mars would be so high.

Intending to sketch an interesting area to the east of the prominent Apennine
crater Conon, including Lacus Felicitatis, I discovered that the scale of the
sketch on PDA was not sufficiently small enough for me to depict the very finest
detail with confidence and precision. Besides, there was so much detail on offer
that I decided to sketch the entire region of the Apennines covered by the PDA
screen to the scale of the original drawing, rather than starting again to a
more convenient scale. So, in view of the scale, plus the not-too-good seeing
conditions and the wealth of detail sometimes overwhelming the senses, this is
just a general impression of a most complicated area. Complicated mountainous
areas are among the most difficult of lunar terrains to capture well in a
drawing. Lacus Felicitatis formed a striking lozenge-shaped low-lying area amid
uplands to the north and south; several ridges ran along the feature and the
crater Yangel was clearly visible at its eastern edge. Much of the landscape
here was clearly seen to be radial to the Imbrium basin. Rima Conon was visible
and Mons Bradley was very bright. To the north, Aratus was visible but Galen
seemingly lost amid the jumble of shadows.
