Star Watching Network for the Summer of FY2007 to be Held and Results of FY2006 Winter Star Watching

July 9, 2007

The Star Watching Network is a nation-wide simultaneous star observation activity using familiar means, such as binoculars and cameras or with naked eyes. This project has been conducted twice a year (summer and winter) since 1988, aiming at stimulating the interests of participants toward a clean and clear atmosphere without any light or air pollution. The Ministry of the Environment (MOE) intends to widely publicize the significance of clean air through this project. The MOE seeks to foster favorable outdoor lighting set-ups by carrying out measures to diffuse lighting installations, such as those with subdued lighting or with less upward light spill, and to eventually improve local air quality and contribute to global warming prevention. The Star Watching Network activities are introduced on the MOE website for children (in Japanese). http://www.env.go.jp/kids/star.html 1.
