1 1 Outreach You Can Do to Promote Dark Skies Awareness: Connie Walker (National Optical Astronomy Observatory) and the "GaN" Team GLOBE at Night For Local Leaders of Dark Sky Advocacy… January 20, NSN2011 Telecon

2 2 National Optical Astronomy Observatory Kitt Peak National Observatory Cerro Tololo Inter- American Observatory

3 3 A global problem that people can help solve locally…

4 4 How to bring awareness and a desire to slow down the increase in light pollution? (Cinzano, Falchi, and Elvidge 2001)

5 5 Questions to Consider How do you explain to city dwellers the importance of what theyve lost to artificial sky glow? How can you make them aware that light pollution is a concern on many fronts: safety, energy conservation, cost, health and effects on wildlife, as well as our ability to view the stars? How do you convince them that its worthwhile to take steps, even small ones, to help redress this issue?

6 6 Light Pollution Education at NOAO Students in Grades K-12, Teachers, General Public Both formal and informal settings GLOBE at Night Campaign Dark Skies Rangers activities

7 7 GLOBE at Night Citizen-scientists record the brightness of the night sky by matching its appearance toward the constellation Orion with star maps of progressively fainter stars. Measurements are submitted on-line and resulting maps of all worldwide observations are created. Over the last 5 annual two-week GLOBE at Night campaigns, 52,000 measurements have been contributed from over 100 countries.

8 8 GLOBE at Night Website 5 step citizen science program – simple to participate Background information on key concepts Interactive games Fun quizzes to check proficiency Teacher and Family Guides in 14 different languages Postcards, flyers en español también! Report page Map page with data in various formats

9 9 Match Night Sky to a Magnitude Chart. Match Night Sky to a Magnitude Chart. Estimate cloud coverage. Fill out the observation sheet.

10 10 A more technically accurate approach: using Sky Quality Meters Press start button here: Light enters here: Read-out numbers here:

11 11 Simple Report Form Date and Time Orion data and SQM data Location Cloudiness Tablet/Pad Cell Phone Desktop/ Laptop

12 12 Measurements are downloadable as datasets in various formats can be examined online via Google Earth or other tools used as the basis of research in a class- room or science fair project or even to inform the development of public policy

13 13 Dark Skies Ranger Activities Explorer -Light Shielding Demo -School Outdoor Lighting Audit -Student Symposium Protector Turtle Hatching Activity Wildlife Activity (Insects) Advocate Magnitude Reader Finding Orion, Leo, etc. A Star Hunt Campaign. Ranger (Students present results.)

15 15 Dark Skies Education Kits (600 kits distributed) Materials for a light shielding demonstration Dark Skies Ranger activities Dark Skies Education & GLOBE at Night resources on CD and 2 DVDs Advertising materials (postcards, poster, flyers, etc) Childrens Book: There Once was a Sky Full of Stars Quiet Skies Activity (AM radio & fan) Sky Quality Meter (optional)

16 16 Shielding Helps Minimize Light Pollution

17 17 Types of Lamps Incandescent Fluorescent Light Emitting Diode (LED) High Intensity Discharge Compact Fluorescent Lamp LED Fluorescent High Intensity Discharge Incandescent

18 18 Unshielded and Shielded Lighting

19 19 The Difference Retrofitting Luminaires Can Make

20 20 Lighting Responsibly Shine the light down. See the effect, not the source. Light only where and when needed. Dont over light. Use energy efficient sources.

21 21 Light Trespass Sky Glow 3 Main Types of Light Pollution Glare

22 22 Energy, Safety & Security Human Health Wildlife The Effects on… Astronomical Research

23 23 Data Analysis Comparison of data over time (changes, trends) Comparison to data on population density Search for dark sky oases Monitor ordinance compliance Effects of light pollution on animals or plants Effects on human health Effects on safety, security, energy consumption, cost Tucson, Arizona, USA

24 24 Students Ask: How Much of the Night Sky Have We Already Lost? 5 km North

25 25 City Lighting Inventory by High Schoolers & Amateur Astronomers 1 km N

26 26 GLOBE at Night Data Orion data points plus 500 SQM data points for Tucson, AZ

27 27 Contour Map of GaN Data ( )

28 28 GLOBE at Night + Bat Telemetry Data

29 29 Bat Telemetry Data + City Ordinance Zones

30 30 Looking Toward the Future by Building... An on-line community with Facebook and Twitter – done! On-line tutorials of the Dark Skies Rangers activities – half way done! A web application to submit GLOBE at Night data using mobile devices – help us test the app! More monthly campaigns – on their way! A user-friendly analysis tool on the GLOBE at Night website (WWT & WGBH) – a bright future!

31 31 GLOBE at Night Needs You... 1 To take GLOBE at Night data during both campaigns. 2 To teach and encourage children and adults to take GLOBE at Night measurements. 3 To become a local coordinator that would work with people at a starparty, or in a classroom or 2 or 3... or with visitors at a local park on their participation in the GLOBE at Night campaign. 4 To do the Dark Skies Rangers activities with students to teach them about light pollution issues and lighting responsibly. 5 To use the GLOBE at Night data with other data sets. 6 To work with the IDA in preserving dark skies. 7 To do it all. Mag

32 32 GLOBE at Night Campaign 2011 February 21 to March 6 for both Northern and Southern Hemispheres Uses Orion. March 22 to April 4 for Northern Hemisphere Uses Leo. March 24 to April 6 for Southern Hemisphere Uses Leo or Crux.
