The Rotation Period of the Sun: As Determined from the Motions of the Calcium Flocculi (Classic Reprint) - Softcover
Synopsis
Excerpt from The Rotation Period of the Sun: As Determined From the Motions of the Calcium Flocculi
In measuring photographs distorted in this way the necessary correction for a point at a given distance from the Sun's limb might be taken from a table, readily constructed for a given position of the Sun's image with respect to the axis of the collimator. To define this position, means were provided for making the solar image concentric with the axis of the collimator. Care was always taken to orient the image so that the distorted axis should be parallel to the solar equator in the photograph. For this purpose the whole instrument could be rotated about the axis of the collimator, the direction of the slit being read 03 on a position circle. The parallel lines on the photo graph (due to dust on the slit, which can not be altogether avoided in any form of spectroheliograph when the slit is narrow) were made to serve a useful purpose in the orientation of the image.

The Rotation Period of the Sun (Classic Reprint)
Print on DemandSeller: Forgotten Books, London, United Kingdom
Seller rating 4 out of 5 stars
Paperback. Condition: New. Print on Demand. This book presents insights into the solar rotation period by analyzing the motions of calcium flocculi, yielding a deeper understanding of solar physics. The author uses innovative techniques to measure the movement of these flocculi over time, revealing that they exhibit an equatorial acceleration akin to that observed in sunspots and other solar phenomena. By studying the calcium flocculi, this book contributes to the ongoing discourse on solar rotation and the behavior of various solar features, providing valuable information for astronomers and those interested in the complexities of our star. 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. Seller Inventory # 9781527754041_0
