AURORA

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.
