2018 Summer -- based in part on comments made during section meetings held 7/7 & 8/4:
Light pollution solutions
is a phrase that has been in circulation for a decade or more, signaling that we don't have to quietly endure increasingly bright skies at night. Happily, engineering solutions can produce a win-win result for all (cost effective lighting without glare and skyglow), if we have the will to pursue said solutions. Sadly, metro Denver and Front Range Colorado is awash in skyglow. Why?First, what is skyglow? Arguably it is the summation of all of the glare and light trespass seen all around us in metro areas. Glare and trespass result from mis-aimed light. The night sky over DU's historic Chamberlin Observatory has reached 100 times the natural night skyglow level, which is 5 magnitudes brighter than that background level. Metro Denver consumes over 6 gigawatts of electrical power, and only 2% of that lighting up the night sky means 120 megawatts being wasted, continuously. Can an intelligent civilization persist with that amount of inefficiency? If you’d like to survey city night lighting worldwide, astronauts on the Space Station took a series of images that you can download from: https://eol.jsc.nasa.gov/
What's happening regionally in terms of light pollution solutions (LPS)? The biggest trend is the adoption of LED lighting. "Hotter" LED lights (>3000K) emit excessive amounts of blue light (450 nm) and those blue photons scatter into the sky too easily --- making those lights easily visible in Space Station images. Jack Eastman points out that flat panel LED lighting could be made less harmful with a simple yellow filter overlay to attenuate the blue photons. Regionally, there is some encouraging news: 1. Westcliffe Colorado is an IDA designated dark-sky friendly community. You can find their progress reports at website: https://www.darkskiescolorado.org/ ; 2. Boulder is facing a mandate to begin enforcing their lighting codes, but are revisiting the topic this autumn, according to activist Richard O`Brien; 3. Northern Laramie county Soapstone Prairie open space is applying for dark sky park designation – https://www.fcgov.com/naturalareas/finder/soapstone --- possible site for future star parties?
How can you help with LPS? Here are a few ideas: 1.Whenever and wherever possible, talk up light pollution solutions, and the beauty of the natural night sky. Also, share a view with your telescope and provide LPS messages to the viewer. If you work with kids, compare their clear-eyed ability to count stars within a region like Pegasus or Orion with your own more clouded view due to aging.
2. Ryan Parker has presented a strong idea, that homeowner associations may be far more effective at controlling glare and light trespass than municipal regulators, because enforcement comes about from residents rather than code enforcement folk working overtime. Many neighborhoods already have less-than-smart lighting, so persuading a group to invest in lower impact lights may be a hard sell. However, persistence in advocating smarter lighting can pay off over the long run because light bulbs will fail and light fixtures eventually will get replaced.
3. When you see a construction fence appear, if often has signage allowing you to contact the owner/builder and to advocate for smarter lighting BEFORE they invest in excessively bright, inferior equipment that adds to glare, light trespass and skyglow. Question: what industrial-strength LED lamp suppliers are these builders buying from lately? Can anyone track down and report on what specific equipment is being added to roadways and uplighted buildings? In that case, we might be able to talk with the suppliers and manufacturers about their product and why lower temperature LEDs or yellow-filtered LEDs are preferable.

Sad news from remote Perry Park (SW corner of Douglas County, CO) - skyglow has gotten annoyingly bright due to unrestrained development throughout the Front Range cities - from Colo Springs to Denver and the inter-mountain towns expanding unsustainably... contact: chrisdunmall at comcast.net was inspired to write an article for the Sentinel because" I like to be able to step out my door and see the awesome night sky. Apparently other people value that opportunity as well, just as they value the open space, wildlife, trees and rocks that we are blessed with here in Perry Park. I hope that by using outdoor lighting smartly we can preserve our dark night skies and keep some of the urban sky glow well away from out homes."

https://aas.org/posts/news/ 2017/03/aas-council-issues- new-resolution-light-pollution --
.
...
" Local action? Here are some ideas:
**If your city or town has not yet switched its streetlights to LEDs, quick! Contact your mayor, city councilor,
planning office, and/or department of public works and make sure they know about the basic rules of good
outdoor lighting (see above) before they make a mistake they'll be stuck with for 20 years. Emphasize the
serious threats to human health that bad outdoor lighting poses: disruption of circadian rhythms, suppression
of melatonin, and elevated rates of cancer, diabetes, and obesity. Give them the latest illustrated info brochures from the IDA.
**Form an outdoor lighting advisory committee in your city or town. Include not just astronomers, but also
experts in, or at least people concerned about, public health, public safety, wildlife, and energy savings.
**Help draft an outdoor lighting ordinance that reflects current best practices, including proper treatment of LED
lights. The IDA website has useful resources including a Model Lighting
Ordinance — you don't have to start from scratch.
**Get in touch with existing environmental organizations, such as local chapters of the Sierra Club,
the Appalachian Mountain Club, The Nature Conservancy, etc., teach them about the importance of controlling
light pollution for the health and welfare of wildlife, and enlist their aid in spreading the word.
**Contact the environmental studies, geography, architecture, and/or urban planning departments on your (or on
a nearby) campus and educate them about the far-reaching hazards of light pollution and the importance of good outdoor lighting.
**Visit a local elementary, middle, or high school and teach kids about light pollution. The IDA and the Globe at Night
citizen science program offer lots of good teaching resources."

Studies have shown that such light, especially from the blue part of the spectrum, inhibits the body’s production of melatonin, a hormone that helps people fall asleep. Options are growing for blocking blue light, though experts caution that few have been adequately tested for effectiveness and the best solution remains avoiding brightly lit electronics at night. etc.

20141024 - letter in support of dark sky designation for Colorado towns of Westcliffe and Silver Cliff:
Dark Skies, Inc., P.O. Box 634, Westcliffe, CO 81252
On behalf of the Colorado Section of the IDA, I am writing in support of the nomination of the adjoining Towns of Westcliffe and Silver Cliff as the first International Dark-Sky Community in Colorado. Approval will make these towns the highest in altitude of any designated. It has been an inspiration to be aware of the local group, Dark Skies, that has been working diligently to reduce the light pollution of Colorado’s wonderful “nightscape” of star-filled night skies. The protection of this valuable resource to both towns has been a 15-year journey of which both Dark Skies and the residents can be proud. These towns serve as a crucial counter-example to the wanton and relentless destruction of dark skies occurring across much of Colorado.
Viewing the nightscape from an isolated refuge and dark location like these Colorado towns can provide a transformative experience of unparalleled beauty. This sense of awe, that most of human history has experienced, has been lost to urban dwellers. Only through protection of remaining areas like Westcliffe-Silver Cliff, can residents and visitors continue to marvel at the view. Because economics matter in success of this preservation effort, designation is key to promoting “eco-tourism” - which can become an important part of the towns’ economic success. In parallel, the long-term protection of the nightscape is dependent on the towns’ enforcement of non-polluting, shielded exterior lighting language in their building ordinances. Designation can help provide additional incentive for these towns to act to protect their special resource.
Certification of the Towns of Westcliffe and Silver Cliff will also reduce the impact of light pollution on migrating and resident bird populations that use various aspects of the night sky for their instinctive behaviors. It will also reduce the negative effects on the natural circadian rhythm of creatures, including humans, that are important for long-term health. Urban dwellers need to wake up to these impacts on all living things within the zone caused by their excessive lighting and related pollutions.
I am a proud supporter of Dark Skies’
certification effort for the Towns of Westcliffe and Silver Cliff.
It will reduce the impact of light pollution and I consider it as a
transcendently valuable example to
all communities in Colorado to think and follow this path of light pollution
solutions.
Astronomically,
Success! See http://www.darksky.org/assets/Night_Sky_Conservation/Communities/WSC_IDSC_press_release_FINAL.pdf --contacts therein.

20140906 - In Cities Across Texas, Activists Battle Billboard Companies
by JOHN BURNETT/NPR
Text: http://www.npr.org/2014/09/06/346153394/in-cities-across-texas-activists-battle-billboard-companies
Audio: javascript:NPR.Player.openPlayer(346153394, 346299218, null, NPR.Player.Action.PLAY_NOW, NPR.Player.Type.STORY, '0')
"The Highway Beautification Act will be 50 years old next year. As envisioned by Lyndon and Lady Bird Johnson, it was supposed to protect the natural landscape from billboards.
"Ever since its passage, scenic activists and billboard companies have been at war over the views along American highways. The outdoor advertising industry says its signs are informational, and helpful to local businesses. Open-space advocates call them "sky trash" and "litter on a stick."
"The battle continues today. You can see it on the roads of Texas, where more than 350 towns and cities have banned new billboards — but billboard companies continue to push for taller and more technologically advanced signs.
etc...
Notes related to the CDOT/electronic signage policy review meeting, 8-28-2014:
(1) strategically, although CDOT and State policy presently only cover "off-premise" electronic (LED) billboards, rules made at this level may be adopted by local jurisdictions to encompass the anticipated flood of similar signs "on premise" appearing at local businesses in your town.
(2) how bright is an LED billboard capable of being? Brightest in the region thus far are metro Denver signs adjacent to I-25 north at 58th street, with the brightest being 1,000 "nits" ... just how bright is that? converting to magnitudes per sq.arcsecond (units of the type measured by a Sky Quality Meter), that equates to FIVE mags/sq.arcsec; for comparison, your laptop screen at max brightness might be about 60 "nits" or about 8 mag/sq.arcsec; for comparison, metro Denver SQM readings have been in the 16 to 18 mag/sq.arcsec ballpark, which equate to 3% to 10% of one cd/m2.
(3) if you see a overly bright electronic billboard at night, here's how to make an effective complaints: if it seems to be advertising an adjacent business, it may be an on-premises sign governed by local rules - contact the planning department or engineer of the town or city involved; if the sign appears to not be associated with an immediately nearby business, it may be an off-premises sign governed by state regs, in which case you can call the CDOT hotline, 303-757-9485, or online at dot AT state.co.us .
(4) Colorado section of the IDA believes documenting problems helps in their solution, and so we extend an invitation to submit your smart phone images of overly bright signs at night to the email address colorado.ida AT gmail.com and be sure to include date, time, address and any information you have about the problem (e.g. glare or other disabling aspect). We will try to share the digital info with appropriate authorities for resolution.

"I have left voicemail messages with Northern Colo. Astronomical Society. Denver Astronomical Society and Colorado Springs Astronomical Society with Alan Gorski. I left them messages this morning on the meeting plans of CDOT, encouraging them to register, and inviting them to call me. If you have any connections with them and want to reinforce my message, please do.
"One objective of us should be for CDOT to not rush to judgment on nits vs. footcandles and levels, unless of course they agree on the use of nits and a level of 100 at night. I doubt they will adopt that. However, I am concerned they may stick with their preliminary judgment in favor of footcandles and 0.3. If they are still leaning that way I hope to persuade them to do more research, do not accept the limited research they have done, based largely on what has been submitted by the billboard industry and me. If the rest of CDOT is using nits for highway lighting design, then why not for roadside advertising? If CDOT has not done field testing of luminance and illuminance, it would seem good regulatory practice would be for CDOT to conduct independent research of existing static and electronic signs.
Thanks for your participation.

August 2014 --Westcliffe
and Silver Cliff applying for Dark Sky Community Certificat
I
just wanted to let you know that our Dark Skies group will be going public
next month with our plans to seek IDA Dark Sky Community certification for
Westcliffe and Silver Cliff (we are calling ourselves "The Cliffs"
for this application). As you may know our group has been quite active
working on local dark skies projects for a number of years. We believe
we can already meet most of the IDA requirements for certification as a result
of these activities. Our primary hurdle will be to get the two
communities to enact lighting ordinances to meet IDA requirements.
Westcliffe
has hired a "Main Street Manager" to help with the community's
economic development efforts. Dark Sky Certification is expected to be
one of this manager's first projects. We will be giving a presentation
to the Westcliffe Town Council at their meeting on September
8 to
let them know what we are doing. Once our plans are made public at this
meeting I wouldn't be surprised if the press or others might contact IDA (and
perhaps you as IDA coordinator) for more information.
As
IDA's State Coordinator I am not sure how much you are involved in the
certification process. However, we certainly would like to solicit your
support and guidance as we go through this. I know some parks are
working on certification but I do not know if any other Colorado communities
are actively working on it at this time.
I
will be serving as the IDA contact for our group. Our current Chairman
in Jim Bradburn.
If
you would like to discuss this more I would be glad to call you (please let me
know the best number to call). You can also call me anytime at (719)
285-4480 or
reach me by email. Thanks,

To colorado.ida AT gmail.com, Amee AT darksky.og
[update 2/20: from john@darksky.org
I am the IDA Chapter Leader for Santa Barbara County, CA. We recently visited the new Chimney Rock National Monument near Pagosa Springs. Based on the name, I was not sure what to expect but discovered it was an archeoastronomy site. It is located in a very dark part of Colorado and the visitor area looks like it is dark sky compliant, too. While there I talked with the volunteer in the very small visitors center and then with our volunteer tour guide. I mentioned to both of them the IDA Dark Sky Park awards and suggested they apply. They were a bit hesitant and explained that it was the volunteers who had pushed through the site's designation as a national monument in 2012. Now 18 of the volunteers are the interpretative "staff" from May-September (and beyond for schools wanting tours) so they are feeling overwhelmed with work. I learned that the change to a monument has not yet been accompanied by additional funds so the US Forest Service is operating it on a shoestring with the volunteers also continuing to do significant fundraising. As you can imagine, I am very impressed by these volunteers as well as this amazing monument. It is such a unique site that it would be a jewel in IDA's recognized parks. I am wondering if you might be able, over time, to work with them on an application. Please visit the monument's website, if you have not already visited the monument itself, to learn why I found it so unusual. (www.fs.usda.gov/detail/sanjuan/specialplaces/ and www.chimneyrockco.org).
Reply: Hello Nancy, Amee:
Thanks for the contact about Chimney Rock and its potential as a Dark Sky heritage site. The loosely organized Colorado section indeed may have members in the Four Corners area who could personally lobby with USFS and others toward that goal. If Amee could share with me a current membership roster, we could share your suggestion and enlist the extra help, along with what I can do from the distance of Denver to Chimney Rock. Perhaps a conference call would be a useful next step as well.

Reply: Hi Triana. Metro Denver has criminally excessive amounts of badly done lighting that produces glare, trespass and skyglow. Denver city has enacted some progressive lighting regulations, but those have extensive exemptions for businesses – Denver building code details start at denvergov.org: http://www.denvergov.org/tabid/436473/Default.aspx# and

Other towns in metro Denver have assorted building code requirements – see http://www.iescu.org/lightingcodes.htm
You might call your city planning department and ask what can be done about wasteful lighting practices in your area, and see what might be next steps. Key to it all is educating anyone who will listen that we can be smarter about how we use nighttime lighting. Hope this helps.
