Abstract
Light pollution (LP) can disrupt and/or degrade the health of all living things, as well as, their environments. The goal of my research at the NOAO was to check the accuracy of the citizen science LP reporting systems entitled: Globe at Night (GaN), Dark Sky Meter (DSM), and Loss of the Night (LoN). On the GaN webpage, the darkness of the night sky (DotNS) is reported by selecting a magnitude chart. Each magnitude chart has a different density/number of stars around a specific constellation. The greater number of stars implies a darker night sky. Within the DSM iPhone application, a user must put the iPhone above his/her head, orient the camera up towards the sky, while ensuring the phone is level, before telling the application to take a snapshot of and measure the DotNS. LoN is an Android application, which asks the user to try and locate at least seven different stars in the night sky. The stars vary in magnitude of brightness. Once an observer specifies whether or not they can see the stars, then the LoN application calculates the DotNS. All DSM, LoN, and GaN measurements were juxtaposed against handheld and stationary night sky quality meter readings, which are scientifically calibrated to exhibit minimal error. Nevertheless, all three applications offer Dark Sky conservationists a window into an extraordinary future. With students, teachers, and community members recording LP data internationally, more sites can be identified as either: Dark Sky certified or in need of night sky conservation/education/legislation.
