(Edward Charles) 09027538 A Plan for Securing Observations of the Variable Stars Produced by Walter MacDonald II "A Plan for Securing Observations of the Variable Stars" by Edward C. Pickering is a scientific publication written in the late 19th century. This book outlines a systematic approach for amateur and professional astronomers alike to observe variable stars, emphasizing the importance of collaboration and structured methodology in astronomical research. The content is primarily focused on the classification and observation techniques for various types of variable stars, making it a significant work in the field of astronomy. The book begins with an encouragement for observers, particularly amateurs and women, to engage in the study of variable stars and contribute valuable data to the scientific community. It categorizes variable stars into several classes based on their brightness fluctuations and provides detailed instructions for observing and reporting observations effectively. Pickering discusses the importance of accurate measurements, establishing a standard method for documenting findings, and coordinating efforts among a broad network of observers to ensure comprehensive data collection. Overall, it presents a plan intended to expand astronomical knowledge through collaborative observation efforts while training a new generation of skilled observers.
