For the majority of amateur astronomers, who live at the latitudes of North America, the British Isles and Australia, the aurora is a relatively infrequent visitor to the night sky. Major displays visible to the southern United States or the south of England occur perhaps 20 times in each 11-year sunspot cycle. When they occur, such auroral storms are a source of great interest and excitement. A number of books highlighting the impact of auroral/geomagnetic storms on communications and satellite technology have appeared in recent years. None, however, has addressed the observational angle. This new book addresses a gap in the literature, offering an explanation of the aurora's causes, how the occurrence of major events may now be predicted, and how amateur observers can go about recording displays.

Transient phenomena are short-lived astronomical events, unusual in a science in which time is more often measured in millennia than milliseconds. There is a fascination with transient phenomena, predictable or otherwise, that astronomers of all abilities share. In Meteors, Comets, Supernovae, Neil Bone gives guidelines for observers, including the best possible periods (months or years) to see seasonal but unpredictable phenomena like meteors and sunspots. Recording such outbursts involves visual observing techniques, photography, and even the relatively new field of the video recording of meteors, which are also examined in detail. The book also includes material about phenomena that occur in the lower atmosphere (such as "ozone eaters", nacreous clouds, solar and lunar haloes), which although not strictly astronomical in their nature attract the attention of dedicated sky-watchers.
