Meteors and How to Observe Them pdf epub mobi txt 電子書 下載 2024
The focus of this book is to introduce the novice to the art of meteor observing. It explains in straightforward language how best to view meteor activity under a variety of conditions, regardless of the observer's location. The observing conditions for each meteor shower are vastly different from each of the Earth's regions and this book would be valuable to any potential observer from Australia to Alaska. The calendar chapters list activity as it occurs throughout the year. The list is limited to showers that the amateur observer can actually see (some sources list radiants that are impossible to observe without photographic or video methods). Not only are the annual showers discussed, but the random sporadic meteor activity is also included for each region. This is important, as there are many more nights throughout the year when the sporadic background will provide more activity than that provided by the annual showers!
Robert Lunsford has had forty years experience viewing meteors and meteor showers, and is a member of the American Meteor Society (AMS) and the International Meteor Organization (IMO).
