Re: [Utah-astronomy] Replicating a hissing meteor
I would be honored to do the experiment of replicating a hissing meteor at next month's meeting. Since there is so very little smoke involved I wouldn't worry about setting any fire alarms off. Since the "rocket" only flies the distance of about a foot, there's no worries about burning down the building either. We would have to have everyone gather in close so that they could hear the hiss. I did this demonstration some 6 years ago for a group of visitors attending a Persied meteor watch at Great Basin. They loved it! Hopefully some of those attendees still go outside at night in hopes of hearing one for themselves. Tom Sevcik

what ever happened to the yearly "show and tell" and SLAS meetings?
Yes, demos would be great. Maybe someone from U of U Physics could
present something.
Would need to be careful with anything that produces smoke, though.
Years ago when I was still with Hansen Planetarium I did such a demonstration in the church history building and ended up setting off the building's fire alarm system which, among other things, shut down the elevators. Kind of funny now but at the time there were a bunch of very annoyed people.

Tom. I think you need to demonstrate that at a SLAS meeting. It would liven things up. Contact Roger Fry.

The last one of those I attended was upstairs at Hansen planetarium. It's definitely been awhile!

I may head up to Mountain Meadows this weekend if the clouds and some of the moonlight go away. I need to hit some spring doubles. I need higher altitude for better seeing. Mountain Meadows is on highway 18 north of the Pine Mountain turnoff.

Thank you Debbie I will try it out tonight or tomorrow. I am watching the clouds for tonight.

Go out to LaVerkin and get on highway 9 to Zion. There is a turnoff about a mile past the LaVerkin Overlook with a stop sign. Go towards the dam and you will see a dirt cul-de-sac there. Perfect for observing. No drunks, no ATV's, just an occasional sheriff there.
Good Luck,
Debbie

Hi, Debbie Do you have any suggestions On where to observe in the St. George area? It is a bit cloudy right now but perfect weather otherwise. I am at the KOA north of Washington. Utah

Hi, All Weather is beautiful down here in St. George. My wife and I will be here for a week. Spring break for canyons school district. Hope to get some astrophotography started while I am here. Hope all the snow is gone up north.

I like it. I am not on the board this year so I can not say what would be approved. After my last go around with the Chinese laser company this sounds interesting.
When I belonged to the ham radio club, we had once a year meeting called home brew. It was fun and you never new what someone was going to bring to show. Some were good others not.

I'm still willing to do the laser pointer brightness comparison test that I offered the SLAS board about ten years ago, and was summarily refused at the time. I'd have to rebuild my test apparatus, since I threw it out when I was told that the club wasn't interested in a laser demo and brightness comparison of different brands and output ratings. It involves the audience rating beam visiblily only (the dots are projected into a light trap and are not visible) and ranking all the lasers accordingly, then the results are tabulated and revealed at the end of the test. Audience members do not know which laser is which before or during the test. They only get to see the beams, side-by-side, up to six at a time on my original test-stand.
Were I to rebuild it, I'd probably go with 4 lasers simultaneously. Winners of each group of 4 would then go up against each other in a final round. SLAS members would be encouraged to bring their own laser pointers to see how they stacked-up against others in the marketplace.
The SLAS president at the time told me "All laser pointers are the same."

I personally would like to see more demonstrations of almost any kind that are astronomy related at SLAS meetings. I think demonstrations related to astronomy are hard to come by and I am a hands on kind of guy.
