This 1986 book presents a series of computer-drawn maps and tables for all total and annular eclipses of the Sun calculated to have been observable in East Asia in the 3400 years from 1500 BC to AD 1900. The study of past eclipses is a useful tool in both geophysics and chronology, for example in determining the long-term behaviour of the Earth's rate of rotation. The eclipses of the Sun that occurred in East Asia - notably in China, Korea and Japan - are particularly useful because numerous reliable written records of them are extant. The book will be of interest to professional astronomers whose work can benefit from long-term historical data, especially those interested in studying the Earth's rotation and to historians of Chinese astronomy. It will be an essential reference work for research libraries.

Solar and geomagnetic variability are of considerable interest for scientists of many different persuasions and indeed one has the distinct impression that for the sun at least, there is direct relevance for mankind in general as the interrelation between solar and terrestrial phenomena is starting to be appreciated. From the vast time scale of interest in the variability field, attention was confined to the last 10,000 years in a NATO Advanced Research Workshop held from April 6 - 10, 1987 in Durham, England, and the present publication comprises the lectures given there. Such a Workshop was very timely in view of the impressive new data available from 14C analysis in dated tree rings and lOBe in polar ice cores, from natural palaeomagnetic records in lacustrine sediments and from archaeomagnetic material. Also to be mentioned are new studies of historical accounts of naked-eye sunspots and aurorae. All the data have contributed to improvements in under standing the relative variations of solar properties, the geomagnetic field and climate and it is hoped that this volume will convey the flavour of these advances in knowledge. A feature of the Workshop was the lively discussions which followed so many of the papers. There were several instances of healthy disagreement and this is reflected in the opposing views presented inanumber of the papers published here."
