Robb Walker: One Dark Sky

OneDarkSky is proud to participate in ALCon2012 by providing public outreach services. The evening of July 4, the Marriott Lincolnshire will host fireworks and a star party in honor of ALCon2012. The event is free and open to the public. OneDarkSky’s Robb Walker will be at your service to highlight the celestial wonders of our night sky.
Though the event officially begins at 8:30 pm, I will arrive and set up around 7:00pm for a bit of solar observing before the main event. So, arrive early if you’d like to take a look at our neighborhood star and see how it’s gearing up for its Solar Maximum in 2013. Once the sun sets and the stars come out, we will begin a celestial tour of the night sky to include (but not limited to):

Saturn
Mars
The Moon
Double and Multi-star Systems
Globular Star Clusters

After an intermission for a wonderful fireworks display, we will continue the “Oohs” and “Ahs” as we peruse the jewels of the night sky. If the weather cooperates and the sky is nice and calm, we’ll try peering a little deeper and see if we can check off some of the objects on the ALCon 2012 Observer’s Challenge list. In addition to telescope observing, we will also enjoy wide-field views with our naked eyes as we trace out constellations and asterisms and simply enjoy the majestic views of our greatest natural resource, the Dark Night Sky!

The New Zealand International Starlight conference will take place at Lake Tekapo, New Zealand in June 2012.

This conference is recognized by the Starlight Initiative as the third of a series started in 2007 on the island of La Palma with the World Conference in Defence of the Night Sky and the Right to Observe the Stars, where the Starlight Declaration was adopted. It will address themes concerning

• the defence of the quality of the night sky,
• the right to observe the stars, the heritage of starlight,
• the issues of light pollution, the protection of observatory sites,
• the benefits of public outreach in astronomy and
• the cultural aspects of visual astronomy.

The Starlight Conference in New Zealand has been planned in conjunction with a bid we recently submitted to the International Dark-Sky Association for a Dark-Sky Reserve to be recognized in the Mackenzie Basin region around Lake Tekapo, and also in the nearby Aoraki/Mt Cook National Park. A Starlight Reserve for the Mackenzie Basin was also proposed in the recent IAU-ICOMOS Thematic Study. We will discuss the concept, implementation and benefits of Starlight Reserves as a means of protecting the night sky, with the benefits for public outreach and astro-tourism, and for astronomical research.

In addition, several radio astronomers have pointed out that the issues of radio-frequency interference have much in common with issues of light pollution. We will therefore expand the topics under discussion to RFI and the development of radio-astronomy in New Zealand, especially the selection of radio-quiet sites. This is topical as New Zealand may participate with Australia in the Square Kilometre Array (SKA) radio-astronomy project.

Earlier Starlight meetings were held at La Palma in April 2007 and in Fuerteventura (both in the Canary Islands) in March 2009. The New Zealand meeting will continue the progress made at these earlier meetings.

“I am a night sky enthusiast,” said Walker, who grew up in Mount Morris, Ill. As a child, he was “really into” astronomy and loved lying on a blanket in the backyard, just watching the stars.

“I could see the Milky Way and lots of stars,” Walker said. “Then I grew up, went into the Army and moved out to the suburbs,” and didn’t think much more about those nights looking at the sky.

Two years ago, however, when his then-4-year-old daughter asked him questions about the stars and planets, it re-ignited that passion, he said.

Walker (no relation to this reporter) got a telescope and began watching shows about stars and planets on TV. Walker and other Chicago-area amateur astronomers do what they call “sidewalk astronomy,” setting up telescopes outside the Adler Planetarium in Chicago and offering passers-by a chance to see a star and the planets on their own.

He also realized that his daughter, now age 6, probably won’t have the chance to grow up seeing the stars and planets the same way he did — because of light pollution.

So Walker founded the website www.OneDarkSky.com, a site dedicated to amateur astronomy and the night sky in general.

He and others like him want to promote turning off lights in the cities at night, to give others the opportunity to really see what the night sky can be.

Some may say that if he wants to see the night sky, he should just drive out to the countryside — that the city is a place of bright lights and that nothing can, or should, be done about it.

But he suspects those people have never really seen what the sky can look like at night, Walker said.

Smart lighting

Night sky enthusiasts say they are not trying to make the U.S. or the Chicago region into a picture of North Korea — nighttime shots of nothing but blackness over the land.

“We are trying to educate people. What we are looking for is smart and responsible lighting at night,” Walker said.

The lights in parking lots that light the sky but not the parking lot, the neighbor’s yard light that stays on all night, the streetlights that are on from dusk to dawn with no shielding from the night sky — all those cause the light pollution that blocks views of the stars.

If there are laws about noise pollution — not keeping neighbors awake with noise from parties — then why, Walker asks, can a neighbor’s yard light be kept on all night, shining into his house?

He had one neighbor whose backyard light was so bright that even more than a block away from his home he could use that light to cast shadow puppets for his daughter.

Lights on all the time also give residents a false sense of security, he said. One United Kingdom study he referenced showed that crime went down when the lights were turned off at night — the criminals didn’t like being out in the pitch black either, and flashlights just drew attention to their actions, Walker said.

Targeting pollution

There also is a push in Cook County and the Cook County Forest District to reduce the amount of light pollution in the county, Walker noted.

“The Cook County Board and the Forest Preserve District of Cook County are considering a lighting ordinance that celebrates starlight and aims to reduce the light pollution so prevalent in the Chicago metropolitan area,” he said. “The ordinance has already been presented and a vote is scheduled for the beginning of February.”

Voters in Campton Hills approved of such a “dark sky” ordinance in a 2009, and Barrington Hills has passed local rules limiting light pollution.

Walker, several friends in the amateur astronomy community, and other like-minded organizations “are preparing for a grand celebration of our night skies in 2012.”

In July, the Astronomical League will host its annual conference in Chicago,

Called ALCon2012, the conference corresponds to both the 150th anniversary of modern astronomy in the Western Hemisphere and the 175th anniversary of the city of Chicago, Walker said.

Light pollution is any adverse effect of artificial light, including sky glow, glare, light trespass, decreased visibility at night, energy waste, and more.
