BAA members may be interested in the work of the U.K. Dark Sky Partnership (UKDSP). This is an informal organisation at the moment and has been going for about two years. Bob Mizon was an early supporter and enthusiastic about its potential for a united approach to working with parliament. The CfDS believes this organisation is currently the best opportunity to achieving better planning and other legislation aimed at reducing light pollution. It represents many people in professional, voluntary and local communities, so is not quite as easy to ignore as a group of amateur astronomers. BAA CfDS has contributed to funding and organisation, including the participation of the UKDSP in the Local Government Association exhibition event in July.
