The Sun and How to Observe It

Without the Sun, all life on Earth would perish. But what exactly do we know about this star that lights, heats, and powers Earth?

Actually, we know quite a lot, thanks mainly to a host of eager solar observers. Looking directly at the Sun is EXTREMELY hazardous. But many astronomers, both professional and amateur, have found ways to view the Sun safely to learn about it.

You, too, can view the Sun in all of its glorious detail. Some of the newest, most exciting telescopes on the market are affordable to amateur astronomers or even just curious sky watchers, and with this guide to what the Sun has to offer, including sunspots, prominences, and flares, plus reviews of the latest instruments for seeing and capturing images of the Sun, you can contribute to humankind's knowledge of this immense ball of glowing gases that gives us all life.

For a complete guide to Sun viewing, see also Total Solar Eclipses and How to Observe Them (2007) by Martin Mobberley in this same series.

Auteur

Jamey Jenkins has been a regular contributor to the Sunspot Program of the American Association of Variable Star Observers (AAVSO) since 1990 and an active observer for the Association of Lunar and Planetary Observers (ALPO) Solar Section since 1998. He has been Assistant Section Coordinator of that group for the last three years. He has also published numerous articles and images in Sky & Telescope and The Strolling Astronomer.

Résumé

In Part 1, the book describes the very latest thinking on solar physics in (mostly non-mathematical) detail, incorporating the latest results from research concerning the structure and behaviour of the Sun. There is particular emphasis on the surface features visible from the Earth, and how these are the result of the extraordinary processes that are taking place within the Sun.

In Part 2, the book details the techniques for observing and imaging the Sun with commercially-available equipment. The many recent advances in optical equipment now allow amateur astronomers to observe phenomena that until recently could only be seen with the extremely expensive equipment available at universities and research observatories notably H-alpha and Calcium-K telescopes.

This is a completely up-to-date solar observing book, while providing the science background necessary for an understanding of the observations with the latest equipment. It also features the most complete solar observing and imaging guide available.
