Globe at Night Spotlights

Amy and John

Our Globe at Night Spotlight this month features Amy Juan and John Kanemoto, two undergraduate students who participated in light pollution research at NOAO this summer. Amy is a Research Experiences for Undergraduates (REU) student at the University of Arizona’s Integrated Optics for Undergraduate Native Americans program and is a member of the Tohono O’odham Nation. John is a part of the STEM Teacher and Researcher (STAR) program, a nine-week summer research internship run by the California Polytechnic State University for aspiring K-12 math and science teachers. Amy and John worked together to determine how well we can measure levels of light pollution using several different devices, including a DSLR camera, a handheld Sky Quality Meter (SQM), the “Loss of the Night” app for Android phones, the “Dark Sky Meter” app for iPhones, and the Globe at Night Webapp which measures the “Naked Eye Liming Magnitude”. They took data from these devices at sixteen locations around Tucson, AZ. They will compare their measurements to those taken over the past year by six SQM data logging stations. Way to go, Amy and John!

VBS Turtle activity

Our second Spotlight this month features the Trinity Presbyterian Church in New Brunswick, New Jersey. Their Vacation Bible School adapted our Turtle Hatching activity to teach students from ages 3 to 14 about how light pollution affects turtles and other wildlife. They also connected it to wildlife conservation overall. The children pretended to be turtles and tried to find the moon, but most of the little turtles went to other light sources. The children then came up with ideas to combat the light pollution. After implementing their ideas, almost all of the turtles found the moon! They also learned about efforts to minimize light pollution from across the world. We love seeing our activities adapted and modified!

Cities at Night

Want another awesome way to get involved in light pollution citizen science? Look no further than Cities at Night, a campaign started in 2003 in which citizens classify pictures of Earth taken from the International Space Station! By choosing what is in the picture, you can help identify which city is pictured. This data can help determine which cities have efficient lighting and which may need to be changed.

International Year of Light 2015

The International Year of Light

The United Nations has declared 2015 as the International Year of Light and Light-based Technologies (IYL 2015). A working group for that cornerstone theme was organized and created a call for proposals for cornerstone projects for IYL’s Cosmic Light theme. Five proposals were awarded the Cornerstone Project status, one of which is Quality Lighting Teaching Kits, a program born out of Globe at Night and headed by NOAO. Activities on light pollution issues and solutions as well as accompanying kit resources for those activities, including tutorial videos and Google+ Hangouts, will be the focus of the program. These programs will be run in 2015 for groups associated with the International Society for Optical Engineering (SPIE) student chapters, the International Commission on Illumination (CIE) outreach volunteers, and the International Dark-Sky Association (IDA) chapter members worldwide. Two of the five other Cornerstone Projects are also related to dark skies awareness. Check out the IYL 2015 website for more info!
