Light Pollution at Embry-Riddle: Effects and Solutions for Our Grey Skies

Abstract

Embry-Riddle Aeronautical University (ERAU) has the largest telescope in Florida. Unfortunately, the light pollution at Embry-Riddle Daytona causes a disadvantage for those who use observation resources, such as the ERAU 1-meter telescope. Members of the ERAU Light Pollution Group (within the Astrophysics Research Club) and I present a literature review of their own data collection methods, successes, and our proposed plans for the future. We have already found that light pollution can be mitigated with a few steps. In the Light Pollution Group\u27s work shown at the Discovery Day conference in April 2024, the light intensity was measured by a Unihedron Sky Quality Meter directly above wall lights near the ERAU quad before and after a top cover and yellow light filter were placed on the lights. The difference measured was 1 magnitude, which is about 2.5 times dimmer after the filter and cover were placed, which means light intensity was reduced. Our study not only reiterates past observations of the severity of light pollution, but it also digs deeper into why the methods work (such as why the light filter reduces light intensity). This poster is concluded by using our research to propose other new methods for light pollution mitigation. This work will push light pollution research and advocacy further, hopefully resulting in some changes at ERAU that will benefit astronomers, such as implementing warmer toned lights or light covers around campus
