New pure-white streetlights a blight for stargazers?

Local trials in UK for pure white street lighting [to be rolled out nationwide?] give cause for concern to amateur astronomers and astrophotographers through possible uncontrollable light pollution.

Homer Glen, Ill., Becomes the Third International Dark Sky Community

I'm very excited by this trend. For astronomers like myself, light pollution is a major problem. Most people are just not able to see the nighttime sky like we used to be able to. And there are indications that light pollution will do nothing but continue to become a bigger problem.

Monmouthshire council switches off street light so Goytre teenager can see meteor shower

A keen astronomer from Goytre made an unusual request to Monmouthshire Council last weekend, in anticipation of witnessing a major meteor shower.
15-year-old Amy Jones loves to view the skies at night but has a major problem - a bright lamp situated immediately outside her house. So when she discovered that a Draconid meteor shower was scheduled for the second weekend in October she contacted MCC's Street Lighting Officer, Roger Joy, to ask if the offending light could be switched off allowing her to view the skies unhindered.

Under natural moonless conditions, the National Park Service said it is easy in some areas to see one's shadow from the glow of Venus or Jupiter and, in some cases, from the Milky Way. But the superintendent of nearby Cedar Breaks National Monument said urban development could wash away the night sky with bright lights.

With the power out, it's easier than ever to find things in the night sky

One upside to the power failure is improved conditions for stargazing. Leslie Brown, associate professor of physics and astronomy at Connecticut College, says light pollution is especially bad along the I-95 corridor and hinders observation of the night sky. With the power outages, however, its a little easier to find a quiet spot away from house and street lights and peer into the heavens.
