GLOBE at Night is an international citizen-science event encouraging everyone, students, the general public, scientists and non-scientists, to measure local levels of light pollution and contribute observations online to a world map. This program is part of the Dark Skies Awareness Global Cornerstone Project for the International Year of Astronomy (IYA) in 2009. Its goal is to raise public awareness of the impact of artificial lighting on local environments by getting people involved. Utilizing the international networks of its hosts, the GLOBE program at UCAR and the National Optical Astronomy Observatory, as well as Astronomical Society of the Pacific, the Association of Science and Technology Centers, the Astronomical League and the International Dark-Sky Association, GLOBE at Night is able to engage people from around the world. Data collection and online reporting is simple and user-friendly. During a 13-day campaign in February or March, citizen-scientists take data on light pollution levels by comparing observations with stellar maps of limiting magnitudes toward the constellation, Orion. For more precise measurements, citizen-scientists use digital sky brightness meters. During the campaign period over the last 3 years, 20,000 measurements from 100 countries have been logged. The collected data is available online in a variety of formats and for comparison with data from previous years, Earth at Night satellite data and population density data. We will discuss how students and scientists worldwide can explore and analyze these results. We will provide the "know-how" and the means for session participants to become community advocates for GLOBE at Night in their hometowns. We will also discuss lessons learned, best practices and campaign plans during IYA (March 16-28, 2009). For more information, visit http://www.globe.gov/GaN/.
