Re: Moon School Party - List of potential lunar targets
Here's a list of targets I through together for lunar day 18. This evening the terminator should be at about 57 degrees East lunar longitude. The list cross-references features to Rukl's _Atlas of the Moon_ map numbers and Chuck Woods _The Modern Moon_ book page discussing the feature. http://members.csolutions.net/fisherka/astronote/observed/20051118MoonTarget... Although the school party is for 3rd graders, the list give you some ideas for personal viewing during the party. The major Rukl maps for longitude 57 degrees east, north to south, are: Rukl# LatN LatS 6 70N 50N 7 62N 50N 15 50N 30N 26 30N 15N 37-38 15N 0 48-49 0 15S 59 15S 30S 69 30S 50S 76 50S 60S 75 50S 70S Mars looked good last night from Little Mtn. Pass. It's dimmer, but the seeing and detail was still good from outside the city heat generated rising air currents. - Canopus56(Kurt) __________________________________ Yahoo!

Let me see if I understand it so far, the terminator, that fuzzy black edge looking thing, will be where exactly? ;) I believe even I will be able to find that! ;) You lost me on the rest of it... Why don't you come out and join us tonight Kurt? Maybe we could laser some cars as they come up the hill... ;) The little kids will be serving Hot Chocolate, which is a far cry from what we usually get... See ya about 8:00 p.m.?

I guess were're back on the GOTO vs. the book chart thing. You'd need a Rukl's _Atlas of Moon_. Guess there's no "Crater Plato" button on that controller thing for your LX200 - the one with 147,000 objects.

Thanks for the invite. I'll catch you next season. I'm still on the learning curve with the new EQ mount and Atlas 10. Once I'm competent with the new mount, I'll start participating in the school parties next season. - Kurt __________________________________ Yahoo!

That would be 147,000 INTERESTING objects... I was able to get your complete list of lunar targets in a single field of view. If I want a tour of the moon, all I have to do is stare at it. ;)

The distances between major rings of the major basin impact structures, made by the largest meteor hits, are approximately the square root of 2 (1.414) or the integer 2. For example: Cleomedes Ring 635 km / Crisium Wrinkle Ridge 375km = 1.66 Geminus Ring 1075km / Cleomedes Ring 635 km = 1.69 Pyrenees Mtns Ring 400km / Nectaris Wrinkle Ridge 240km = 1.66 Altai Scarp 860km / Pyrenees Mtns Ring 400km = 2.15 If you want to walk over an Earth analogue to this type of lunar structure, go down to the Upheaval Dome in Canyonlands. http://www.nps.gov/cany/pdfs/island.pdf Originally, geologists thought Upheaval Dome was a salt dome. Then a lunar geologist saw an ariel photo of it and noted the characteristic square root of 2 basin-ring structure - http://www.seismo.unr.edu/ftp/pub/louie/dome/dome-album.html http://www.meteorite.com/impact/upheaval.htm http://www.hohmanntransfer.com/cg/upheaval/dome.htm Reinvestigation lead to a revision that Upheaval Dome is an impact crater. http://www.seismo.unr.edu/ftp/pub/louie/papers/dome/ Upheaval Dome is degraded but looks like the characteristic ring structure of basins on the surface of the Moon. http://www.lpi.usra.edu/expmoon/orbiter/4lo187m.gif
Cleomedas crater . . . Terraced walls; small dome
Some craters are old, large and have multi-terraced walls.
Cleomedas . . . Cut by a rille When craters sit on or near the edge of major basin, as the basin expands and then collapses at the center, the ground on the floors of the craters on the edges of basin tilt towards the basin, and develop large cracks.
Stevinus A crater . . . Conspicuous ray system Some craters are small, young, round, have no terraced walls, but white-rayed ejecta streaks coming out of them, like Meteor Crater in Arizona. http://www.barringercrater.com/
Messier A crater . . . Grazing impact with asymetric impact ray Other impact meteors hit an angle, making weird craters.
The third graders may not get it, but next time you can wow the fifth graders. -:) Enjoy - Canopus56 P.S. - Someday I am planning to try to take a photo of the Moon rising over the rim and central mound of the Upheaval Dome, but maybe it's already been done. __________________________________ Yahoo!

1. The elderly couple watching t.v. from their couch, in the house directly East of the parking lot. 2. The second window to the left on the corner house east of the church. 3. The sheriff's car parked in the north/west parking lot of the church doing paper work, or, running radar. (when he gets back up off the floor, don't let him see where the beam came from. If you have to, hand the laser to one of the 3rd graders and run like hell.) 4. 2nd story window of the beige brick house on the South East corner. The one with the red porch light and all the cars. 5. Anybody walking their dog ON a leash. (It is surprising how is fun it is to watch the dog drag their owners in and out of traffic as they chase the laser around the street.) Do I really have to say it??? Okay then, Just kidding!
