Paperback. Condizione: New. Print on Demand. This book is an extensive study of the Sun produced by the author, the founder of the Kenwood Observatory. Here he describes important solar phenomena not visible to the eye and not shown on regular photographs. This includes the discovery of bright calcium regions that correspond to…hot calcium vapor in the upper part of faculae and in the lower part of the chromosphere. The author coined the term "flocculi" to describe these calcium clouds, as they are not identical in appearance to the underlying faculae. The book delves into the varying level of intensity of calcium vapor at various elevations above the photosphere and explains how changes in the density of calcium vapor impact our observations. It also discusses the structure and composition of the photosphere and chromosphere, offering a unique perspective on solar activity and contributing significantly to our understanding of the Sun. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
