Ken M. Harrison's latest book is a complete guide for amateur astronomers who want to obtain detailed narrowband images of the Sun using a digital spectroheliograph (SHG). The SHG allows the safe imaging of the Sun without the expense of commercial ‘etalon’ solar filters. As the supporting software continues to be refined, the use of the digital spectroheliograph will become more and more mainstream and has the potential to replace the expensive solar filters currently in use. The early chapters briefly explain the concept of the SHG and how it can produce an image from the solar spectrum. A comparison of the currently available narrow band solar filters is followed by a detailed analysis of the critical design, construction and assembly features of the SHG. The design and optimum layout of the instrument is discussed to allow evaluation of performance. This information explains how to assemble a fully functional SHG using readily available components. The software required to process the images is explained and step by step examples provided, with various digital instruments around the world highlighted based on input from many experienced amateurs who have shared their experience in building and using their spectroheliographs. The final chapters provide a historical overview of the traditional spectroheliograph and the later spectrohelioscope, from the initial G.E.Hale and Deslandres concepts of the 1890’s through to the later work by Veio and others. The construction and performance of various instruments is covered in detail, and provides a unique opportunity to record and appreciate the groundbreaking researches carried out by amateurs in the 20th century. This is an absolutely up to date book which fully addresses the watershed, game changing influence of the digital imaging revolution on the traditional spectroheliograph.

The First Edition of The Sun from Space, completed in 1999, focused on the early accomplishments of three solar spacecraft, SOHO, Ulysses, and Yohkoh, primarily during a minimum in the Sun’s 11-year cycle of magnetic activity. The comp- hensive Second Edition includes the main ndings of these three spacecraft over an entire activity cycle, including two minima and a maximum, and discusses the signi cant results of six more solar missions. Four of these, the Hinode, RHESSI, STEREO, and TRACE missions were launched after the First Edition was either nished or nearly so, and the other two, the ACE and Wind spacecraft, extend our investigations from the Sun to its varying input to the Earth. The Second Edition does not contain simple updates or cosmetic patch ups to the material in the First Edition. It instead contains the relevant discoveries of the past decade, integrated into chapters completely rewritten for the purpose. This provides a fresh perspective to the major topics of solar enquiry, written in an enjoyable, easily understood text accessible to all readers, from the interested layperson to the student or professional.

Written in a light and friendly style, this lavishly illustrated book introduces the Sun and its physics, and describes all aspects of the Sun’s interaction with us on Earth. The second edition of this book updates the popular text by providing comprehensive accounts of the most recent discoveries made by five modern solar spacecraft during the past decade. It contains a number of images never before seen in print. Breakthrough observations with the underground Sudbury Neutrino Observatory are also included. The new edition further provides modern interpretations of ozone depletion and global warming.

The Sun is nowadays observed using di?erent techniques that provide an almost instantaneous 3-D map of its structure. Of particular interest is the studyofthevariabilityinthesolaroutputproducedbythedissipationofm- netic energy on di?erent spatial and temporal scales – the so-called magnetic activity. The 11-year cycle is the main feature describing this phenomenon. Apart from its intrinsic scienti?c interest, this topic is worth studying because of the interaction of such processes with the terrestrial environment. A ?eet of space and ground-based observatories are currently monitoring the behaviour of our star on a daily basis. However, solar activity varies not only on this decadal time-scale, as has been attested mainly through two methods: (a) records of the number of sunspots observed on the solar surface from 1610, and (b) the records of 14 10 cosmogenic isotopes, such as Cand Be, measured in tree-rings and i- cores, respectively. The study of the long-term behaviour of solar activity may be comp- mented by the study of historical accounts describing phenomena directly or indirectly related to solar activity. Numerous scienti?c and non-scienti?c d- uments have reported these events and we can make use of them as a proxy of solar activity in past times.

Essential Astrophysics is a book to learn or teach from, as well as a fundamental reference volume for anyone interested in astronomy and astrophysics. It presents astrophysics from basic principles without requiring any previous study of astronomy or astrophysics. It serves as a comprehensive introductory text, which takes the student through the field of astrophysics in lecture-sized chapters of basic physical principles applied to the cosmos. This one-semester overview will be enjoyed by undergraduate students with an interest in the physical sciences, such as astronomy, chemistry, engineering or physics, as well as by any curious student interested in learning about our celestial science. The mathematics required for understanding the text is on the level of simple algebra, for that is all that is needed to describe the fundamental principles. The text is of sufficient breadth and depth to prepare the interested student for more advanced specialised courses in the future. Astronomical examples are provided throughout the text, to reinforce the basic concepts and physics, and to demonstrate the use of the relevant formulae. In this way, the student learns to apply the fundamental equations and principles to cosmic objects and situations. Astronomical and physical constants and units as well as the most fundamental equations can be found in the appendix. Essential Astrophysics goes beyond the typical textbook by including references to the seminal papers in the field, with further reference to recent applications, results, or specialised literature.

When 16-year-old poetry blogger Tessa Dickinson is involved in a car accident and loses her eyesight for 100 days, she feels like her whole world has been turned upside-down. Terrified that her vision might never return, Tessa feels like she has nothing left to be happy about. But when her grandparents place an ad in the local newspaper looking for a typist to help Tessa continue writing and blogging, an unlikely answer knocks at their door: Weston Ludovico, a boy her age with bright eyes, an optimistic smile...and no legs. Knowing how angry and afraid Tessa is feeling, Weston thinks he can help her. But he has one condition -- no one can tell Tessa about his disability. And because she can't see him, she treats him with contempt: screaming at him to get out of her house and never come back. But for Weston, it's the most amazing feeling: to be treated like a normal person, not just a sob story. So he comes back. Again and again and again. Tessa spurns Weston's "obnoxious optimism", convinced that he has no idea what she's going through. But Weston knows exactly how she feels and reaches into her darkness to show her that there is more than one way to experience the world. As Tessa grows closer to Weston, she finds it harder and harder to imagine life without him -- and Weston can't imagine life without her. But he still hasn't told her the truth, and when Tessa's sight returns he'll have to make the hardest decision of his life: vanish from Tessa's world...or overcome his fear of being seen. 100 Days of Sunlight is a poignant and heartfelt novel by author Abbie Emmons. If you like sweet contemporary romance and strong family themes then you'll love this touching story of hope, healing, and getting back up when life knocks you down.
