The newest addition to Durham's skyline, the Jaume Plensa light sculpture "Sleep No More" -- or as fellow local blogger Michael Bacon christened it, Durham's light saber -- drew some opposition after its announcement this fall.
As you'll recall, a small group of local skywatchers opposed the concept from its announcement, forming a group and getting some press attention for their concerns over the light pollution impact on the night sky, a topic that's reared its head in Durham around street light discussions as well.
One of the group's founders, Mark Gibson, decided to check out the light saber on its first night for himself, and found that the impact wasn't so bad, simply because of, well, all the other light pollution we have in the Bull City:
I had to drive to Durham to see the Bridge to the Sky myself. As I got closer to Durham, I kept looking at the horizon to see if I could see the light. I finally saw it when I was in downtown Durham. I don’t think the citizens got the spectacular sculpture they were wanting. It may have been the overpowering interior lights in the building shining to the outside or the stadium style lights at the site of the sculpture. Or could the blue light caused the sculpture to loose the effectiveness of the light. I took out my Sky Quality Meter (SQM) and took some readings. 11.22 at the sculpture site. 15.01 at the field in front of theThe reading on the street where I parked was 10.04. As I drove home I wanted to see if I could see the light from the Airport Observation Deck. I stopped by and could not see it. I got a reading of 18.22 there. Since all the other street lights the city has overpowers this 7,000 watt light bulb it should raise a flag to the citizens that they need to see why the waste so much light.
Gibson's findings mirror my own; I've seen the light, say, on Duke's East Campus (where it looks more like a bat-signal calling some caped crusader to the scene), or driving towards downtown on 147 (eastbound, there's a point where it neatly aligns with the steeple of the Duke Memorial United Methodist Church.) But it hasn't been broadly viewable throughout the sky, for instance.
So this chapter in the public discourse comes to a close -- though Gibson's larger point about light pollution, in Durham and in other cities, remains. Several local neighborhoods have had intensive debates about the value of streetlights, a discourse I don't expect to see end any time soon.
