If anyone finds themselves outdoors tonight, on the west side of the valley near the E Center, cast your gaze toward the Capitol Hill area on Salt Lake's north bench. Ann and I will be conducting our "laser visibility" activity tonight at about 8-ish. You may be able to see my beam if you are near the Capitol grounds or the area above and west of there, below Ensign peak. These beams diverge very little, so chances are not great that you'll see anything unless you happen to be illuminated directly, but you never know. I'm going to try and get a photo or two. This is a repeat of what I did in 1975 with a HeNe lab laser. Stay tuned. __________________________________ Yahoo! FareChase: Search multiple travel sites in one click. http://farechase.yahoo.com

For a Class IIIA, that's probably too far. 3.5 kilometers is FAA tested "no effect" limit (without optical aids). See Tables 3 and 4 in: http://members.csolutions.net/fisherka/astronote/observed/Glptst/discuss.htm... Chuck, not to put a damper on your activities and enthusiam - which I respect immensely - but since you live in a landing corridor and are projecting across the 5-7 kilometer FAA "laser free" zone around SLC Int'l Airport, technically, what you are doing might violate FAA flight orders.

Just want to give you the heads up. - Kurt P.S. - I live in the Avenues, so I'll stick a pair of binos on Ensign around 8:00PM. __________________________________ Yahoo! FareChase: Search multiple travel sites in one click. http://farechase.yahoo.com

A little quick at the trigger! Glad to know I can still hit the send button before I can type a reply... ;) What I was going to say before the "send" button got in the way, is "Don't worry about any rules and regulations Chuck, I don't know anyone who would turn you in for aiming your green laser pointer towards the Capital". Besides, who would be stupid enough to fly that low? ;) How about you Patrick? Do you know anyone who would fly so low? ;)
