This text should appeal to all researchers who have an interest in Leonid showers. It contains over 40 research papers that present some of the first observational results of the November 1999 Leonid meteor storm, the first storm observed by modern observing techniques. The book is a glimpse of the large amount of information obtained during NASA's Leonid Multi-Instrument Aircraft Campaign and groundbased campaigns throughout the world. It provides an overview on the state of meteor shower research for any professional researcher or amateur meteor observer interested in studies of meteors and meteoroids and their relation to comets, the origin of life on Earth, the satellite impact hazard issue, and upper atmosphere studies of neutral atom chemistry, the formation of meteoric debris, persistent trains, airglow, noctilucent clouds, sprites and elves.

The field of ultraviolet astronomy offers unequalled scientific promise yet has not been blessed with a multitude of space missions (as has been the case for other spectral domains). This book contains a distillation of the community's views on the topic and the desires for future observational facilities. As such, it provides the most up-to-date information on the topic of ultraviolet astronomy from a very broad point of view, presenting a compilation of lectures given at a specialist meeting and combining theoretical arguments with observational reports and detailed instrumental information.
