Does the loose nut have a name? Siegfried I have a bug up my butt to grind a 4.25" schiefspiegler. What do you think? I'd be starting with about 180 grit. I have a couple of old plate glass pieces. I wanted to see if Vaughn has some cervitt or zerodur or other low expansion glass.

Leonids

Here's a page from Grand Junction's National Weather Service's site I found while checking the local forecasts for potential observing sites: http://www.crh.noaa.gov/gjt/leonid.htm From what I've seen so far from the National Weather Service and the Weather Channel .com the best outlook for both clear skies and temp is South and West...somewhere like St. George, Las Vegas, Death Valley. Less clear and colder near Delta/Filmore/Torrey/Moab/Mexican Hat. Please let me know if you'd like to find out where our little caravan ends up traveling on Monday. We're thinking of driving somewhere Monday afternoon, checking in at a local motel, going out for the night, coming back and sleeping for a bit before coming back Tuesday. I'll make sure and send out an email right before we head off letting you know our destination. Praise be to the Clear Sky Gods! Dave Bennett dlbennett(a)mac.com

Brent, I would be interested in the class. Using the same logic you have, I thought the winter would be a good time to give this a try. I have 2 blanks that I bought from Dan Cassaro off the net, but they are not the sizes you have indicated below. Mine are 8" and 16". Would it be acceptable for me to attend the class working on one of these. Each have been pre-cut to F7 and F4.8 respectively. If not, I would still like to attend and grind a 10 or 12 inch mirror as you outlined below. I need the experience as I have never tried grinding my own mirror.

I went down to Parowan Gap. At 8:55pm I saw a bright green bolide. It came in just south of Cassiopia. The interesting thing was that it appeared to hit a cloud bank. Just as it reached the cloud bank, it lurched, a little bit broke off and the main meteor continued under the cloud cover. I am not sure this was possible so it may have just been my viewing angle. I eventually went to bed and woke up at 2am. I thought they put on a good show. I counted bursts of 10 or more a second. I also noticed that most of what I saw was looking right at Leo. There were a lot of short bright meteors right near the radiant. The longer ones that I saw were going toward Canis Major. At around 3:50 the clouds got pretty thick. At about 4:30 I went back to bed. I know last year I saw more meteors, but that was without the moon. I think this year may have exceeded last year if we could have seen the dim meteors bouncing all the way across the sky. It was definitly worth the drive to the south. How was St. George? I couldn't leave early enought to get all the way down there.

Hi folks, I got up at 0200 and watched from Farmington. I didn't yawn till dawn like Joe. I saw three in an hour and went to bed when some clouds rolled in. I did log onto NASA TV online, which was doing a special Leonids broadcast, and it was more interesting, and a lot warmer, than looking through thin clouds at the near full moon. I sure am glad I went out to Little Sahara last year! Bob St. Marie

I envy Ron Jones and crew who got out of the city lights. I guess it is really dark out past Aragonite?

Take I-80 East (past Park City exit) to Exit 147. (Rt. 40 East). Stay to the right. The exit splits and there is no stop sign for East-bound Rt. 40. Head East to Exit 4. At the bottom of the exit ramp, go left towards Kamas. Take this road for 1.6 miles to the Peoa - Oakley turn-off. This turn-off will be on your left. You know you are approaching it because there are several "Deer-Crossing Ahead" signs. Since the Deer Crossing is at the turn off, the distances on the signs are also the distances to the turn-off. This is Browns Canyon, but the sign says Peoa - Oakley. Take this road for 4.2 miles, to the Harper Gravel Pit road and sign on the left. (About 1000 feet before you get to the gravel pit road, there will be an orange sign on the right that says truck entrance ahead.) At the gravel pit sign, turn in. There is a gate across the road with a chain. The gate should be open. (But sometimes it will be closed and the chain will be wrapped around the ends of the gate. It is not locked. If so, unwrap the chain, open the gate and come on through. Carefully close the gate behind you and re-wrap the chain.) Go about one and a half miles up this road. There is a mobile home type weighing office off to the left. Just before the weigh office, the road widens and separates into a parking area and the road way. We usually set up in the parking area behind the weigh office. At 01:58 PM 11/18/2002 -0700, you wrote: >>>> Where is Brown's Canyon?
