Optical aurora detectors: using natural optics to motivate education and outreach

Abstract

Natural optical phenomena enjoy a level of interest sufficiently high among a wide array of people to provide ideal education and outreach opportunities. The aurora promotes particularly high interest, perhaps because of its relative rarity in the areas of the world where most people live. A project is being conducted at Montana State University to use common interest and curiosity about auroras to motivate learning and outreach through the design and deployment of optical sensor systems that detect the presence of an auroral display and send cell phone messages to alert interested people. Project participants learn about the physics and optics of the aurora, basic principles of optical system design, radiometric calculations and calibrations, electro-optical detectors, electronics, embedded computer systems, and computer software. The project is moving into a stage where it will provide greatly expanded outreach and education opportunities as optical aurora detector kits are created and disbursed to colleges around our region.

Colors of the Yellowstone thermal pools for teaching optics

“…1 Here we describe a similar interdisciplinary project based on a computer model of the colors observed in the thermal pools of Yellowstone National Park. 2 More than three million people visit Yellowstone National Park in the northwestern United States each year.…”
