Plato (May 3, 2009)
      #3082776 - 05/03/09 01:17 PM Attachment (50 downloads)

I made an observation of Plato and the surrounding region on May 3, 2009 (02:00-04:00 U.T.) using my 9-inch (23-cm) F/13.5 Maksutov-Cassegrain at 352x under average seeing conditions (5/10, with brief moments of 6-7/10). I noted peaked shadows over the floor of Plato (peaks rising up to 1.3 miles (2.1 km) above the crater floor) along with a pair of craterlets ( I noted two to three more craterlets but they were not held steadily). The western section of the this large walled-plain (51.6*N, 9.3*W, 63 miles (101 km) diameter) was brightly lit. The region south of Plato is very complex. Plato was formed approximately 3 billion years ago over the northeastern edge of Mare Imbrium.

Tommy,

Thank you for the compliment on my Plato observation. I was impressed by the amount of detail visible. The best of luck in your own observations.

Love the details of the shadows and crater. I agree with Eric that this is one of your best.

Carlos,

Stunning. That is a beautiful sketch of a wonderful target. Catching the shadows long on the crater floor is a real treat to see live and sketched too. Wonderful work, Carlos.

Wonderful sketch, Carlos. I think I was looking at Plato close to the same time you were--about 04:00 UT. That's a great rendition of the view.

Carlos,

Another very fine sketch which conveys very well the eyepiece view of this wonderful lunar crater.

Carlos,
You are only getting better and better. In this one you are describing the dimentionality of the view rather than just showing the flat look. Something I sometimes find harder than it looks. Keep them coming.

That really is a work of art! Those crater shadows are superbly rendered. Good enough to frame and put on the wall.....

Thank you all very much for the kind compliments on my Plato observation. Plato is a lunar feature that has always intrigued me, especially the issue of the craterlets visible over the floor. This walled plain has interested many lunar observers since the beginning. Transient Lunar Phenomena (TLP) consisting of flashes and fogs over the floor have been noted over time. Although the floor of Plato is rather flat the scene did elicit an added depth contributed to by the walls and surrounding complex terrain. I noted a complex rille system to the east of Plato that I was unable to complete due to the Moon being blocked by my home.

The best of luck in your own observations of the Moon.
