I think it is problem of Urban sprawl, which seems the root of most problems. The article I linked mentioned the problem is expansion south, north is against the mountains. Sun City is on N edge and I have taken a golf cart out to golf courses near my mom to look at comets. It was better than my backyard. I think the lesson is that light pollution ordinances have limited impact if it does not include the same standards to private interest. It is huge waste of electricity at a time when we should take conservation seriously in place of drill baby drill.
Erik Phoenix is the fifth largest city in the United States (behind New York,
Chicago, Los Angeles and, perhaps, Philadelphia. I was there in March. From Mesa, a suburb of Phoenix (like Sandy to Salt Lake), I could see all of Orion (no shield or club - almost, but not quite there) and all of Gemini. Jupiter was blazing. I was dutifully impressed. Their night sky is equal to, if not better than Salt Lake's. The trib article would have mentioned everyone's back yard if Salt Lake had such lighting restrictions. It is my understanding the state of Arizona has adopted lighting restrictions and the cities are moving into compliance. _______________________________________________ Utah-Astronomy mailing list http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy
