MLO intro in Seattle

A promising new weapon against light pollution will receive a formal introduction at an event in Seattle Wednesday. Nancy Clanton, a board member of the International Dark-Sky Association (IDA) and member of the Illuminating Engineering Society of North America (IES), will present a workshop about the Model Lighting Ordinance (MLO) at 10 a.m. October 26 at the Lighting Design Lab, located at 2915 Fourth Avenue South in Seattle.

A workshop on the IDA/IES Model Lighting Ordinance will be held Oct. 26 at the Lighting Design Lab in Seattle.

A task force of the IDA and the IES spent seven years hammering out the details of the model lighting ordinance. It is intended as a guide for environmentally responsible outdoor lighting, and was designed to help municipalities develop outdoor lighting standards that reduce glare, light trespass, and skyglow.

Clanton, who co-chaired the task force, says the process took so long in part because the two organizations started with different sets of goals.

“It wasn’t even a compromise,” she said of the final version of the MLO approved this summer. “We actually blended the goals together and got a really good ordinance that addresses everyone’s concerns.”

The stars aligned to bring this rollout of the MLO to Seattle, according to Scott Kardel, public affairs director for the IDA.

“We’ve chosen Seattle to be the first site partly because Seattle and the Pacific Northwest is a progressive, happening area where people are interested in things like energy conservation,” Kardel said. “Also we have a very active chapter of the IDA, Dark Skies Northwest. It’s a good combination of being able to have our local chapter involved in promoting the event but in an area where we think it has a good chance to have good reception.”

Clanton said the four-hour workshop will give participants a lot of good information about the MLO.

“Here’s what it is, here’s how it was developed, and let us show you some examples of how it could be applied,” was her quick outline of the agenda. “It’s going to be an introduction, answering questions about the different parts of the MLO, and an encouragement for people to bring it to their cities and communities and start looking at adoption.” She noted that the workshop would be useful for city planners as well as for interested advocates who want to learn how to bring better lighting ordinances to their communities.

Clanton said that the city of Plymouth, Minnesota adopted an early version of the Model Lighting Ordinance, which was a big help as they worked through the process. Now Anchorage may be about ready to go to work on adopting the version approved this summer. Both she and Kardel noted that often cities will plow ahead on their own with lighting ordinances, using information from the IDA website, but not telling anyone or availing themselves of the association’s technical expertise. Clanton added that the MLO is not a product that’s ready to adopt off the shelf, but more of a template.

“The model lighting ordinance is supposed to be the technical part of a standard lighting ordinance,” she said, adding that they’ve included placeholder language for intent and the like, but that each community should customize the MLO based on its particular needs. “We had to write this ordinance as if it were a small village or New York City.”

Sky glow is a big deal in Tucson, with Kitt Peak, Mount Lemmon, and Mount Graham observatories in the neighborhood. Kardel said that Tucson, also home base to the IDA, is a prime example for us that lighting ordinances work to curb light pollution.

“We’ve had a big increase in population over the last several decades but have been able to hold on to the level of sky brightness, even with more people and more houses and more lights in the area,” Kardel said. “A good ordinance can do a good job to either hold on to what you have or make things better.”

Clanton gave a shout-out to amateur astronomers for their diligence on these issues.

“The astronomy community has been such a wonderful, vocal voice on light pollution,” she noted. “Without them, I don’t think a lot would have been established. They have been the grass roots in all kinds of light pollution ordinances.”

Cost to attend the workshop is $75 and includes lunch. Sign up here or visit the IDA website for more information.


Science of sci-fi tops weekend astro calendar

Star Wars: Where Science Meets ImaginationA highly anticipated event launches this weekend at the Pacific Science Center. Learn about the science of science fiction by attending the new exhibit “Star Wars: Where Science Meets Imagination.” The exhibit compares the whiz-bang technology of the Star Wars movies and compares it to real scientific breakthroughs of today. How close are we to developing a usable light saber, anyway?

There’s plenty there for Star Wars fanatics, including Luke Skywalker’s land speeder and Darth Vader’s suit, among more than 80 costumes, props, models, and displays from all six movies.

Science Center members are getting a sneak preview today. The exhibit opens to the public Saturday, March 19, and runs through May 8.

Star Wars fans 21 and older can enjoy the exhibit at the Science Center’s Science with a Twist cocktail party next Thursday, March 24 starting at 6 p.m. It may not quite be the Mos Eisley Cantina, but music from the film’s drinking establishment will be played in the center’s Willard Smith Planetarium. Be careful, though. We don’t yet fully understand the effects of riding the Millennium Falcon after consuming a couple of cosmic martinis.

Tickets to Science with a Twist are $20, and $17 for PacSci members.

Dark Sky talk at EAS
The Everett Astronomical Society holds its monthly meeting at 3 p.m. Saturday, March 19 at the Evergreen Branch of the Everett Public Library. Guest speaker Dave Ingram of the local chapter of the International Dark-Sky Association will talk about “Artificial Nighttime Light Pollution:  The Adverse Consequences and Means of Mitigation.”

As the Pacific Northwest’s population grows, so too does the problem of artificial nighttime light pollution in and around our cities. Though photographers, stargazers, and astronomers are familiar with light pollution’s detrimental effect on the night sky, overall public awareness of those negative effects has yet to rise to the level that it has with air, soil or water pollution. This presentation is based on solid, extensive research by the International Dark-Sky Association and by commercial, civic, industrial, government and foreign sources that focus on light pollution from artificial outdoor lighting.

Equinox sunset party Sunday
The spring equinox is at 4:21 p.m. Pacific Time Sunday. Skywatchers will gather to view the first sunset of spring at West Seattle’s Solstice Park. Alice Enevoldsen of Alice’s Astro Info hosts these quarterly equinox/solstice watches, typically under cloudy skies that block the view of the sunset and prevent verification that Old Sol actually goes down in alignment with the markers in the park. But hope springs eternal! The sun sets at 7:22 p.m. Sunday, so the gathering will begin around 7:00.
