Advancing Variable Star Astronomy
Founded in 1911, the AAVSO boasts over 1200 members and observers and is the world's largest non-profit organization dedicated to variable star observation. This timely book marks the AAVSO's centennial year, presenting an authoritative and accurate history of this important association. Writing in an engaging and accessible style, the authors move chronologically through five eras of the AAVSO, discussing the evolution of its structure and purpose. Throughout the text, the main focus is on the thousands of individuals whose contributions have made the AAVSO's progress possible. Describing a century of interaction between amateur and professional astronomers, the authors celebrate the collaborative relationships that have existed over the years. As the definitive history of the first hundred years of the AAVSO, this text has broad appeal and will be of interest to amateur and professional astronomers, as well as historians and sociologists of science in general.
A Scovil Genealogy
The name Scovil, Scovill, Scoville, and Scovel originated in Normandy as Escoville after the town of Escoville, Normandy. The earliest identifiable ancestor of the Scovils was Ralph de Scoville (ca. 1194), a Knight from Wiltshire. John Scovell (1635-1700) was one of the first Scovils to come to America. He settled in Connecticut. His brother, Arthur, also came about the same time and his descendants also settled in Connecticut. Descendants live in Connecticut, Utah Kansas, and Canada.

Eclipse: A Journey to Darkness and Light
According to world-famous astronomer David Levy, an eclipse of the sun “is a natural event with unnatural consequences. In fact, a total eclipse of the Sun has the power to rip through to the core of your being.” Levy should know, having experienced the power of the vanishing Sun first as a child then in 1999 on a ship in the North Atlantic. It was that voyage to the darkness of the disappearing Sun, followed by a rendezvous with a brilliant display of the Northern Lights, that formed the inspiration for this book. Levy recounts the recorded history of eclipses, how they have been perceived by ancient cultures, how they can be predicted, and how best to view them. In addition, he explains the science of solar eclipses and what can be gained by studying them. In a manner accessible to all readers, Levy recounts the story of nature’s most profound displays.
Cosmic Challenge
Listing more than 500 sky targets, both near and far, in 187 challenges, this observing guide will test novice astronomers and advanced veterans alike. Its unique mix of Solar System and deep-sky targets will have observers hunting for the Apollo lunar landing sites, searching for satellites orbiting the outermost planets, and exploring hundreds of star clusters, nebulae, distant galaxies, and quasars. Each target object is accompanied by a rating indicating how difficult the object is to find, an in-depth visual description, an illustration showing how the object realistically looks, and a detailed finder chart to help you find each challenge quickly and effectively. The guide introduces objects often overlooked in other observing guides and features targets visible in a variety of conditions, from the inner city to the dark countryside. Challenges are provided for the naked eye, through binoculars and the largest backyard telescopes.
