Plus Information Leading to Accurate Timings of Lunar and Asteroid Occultations

The International Occultation Timing Association (IOTA) wants you for the most exciting observations you can make – occultations ! Never before has there been an opportunity to contribute to the body of scientific knowledge about the lunar limb profile and the size of shape of asteroids plus a host of other occultation phenomena.
Occultations
occur when one celestial body passes in front of another temporarily blocking its light.
The observation of these "eclipse" events provides important information on the celestial body
responsible for the eclipse.
Chasing the Shadow: The IOTA Occultation
Observer’s Manual is the only
book of its kind that shows observers how to get started in occultations, what
equipment to use and how to predict, make, and report valuable occultation
observations. IOTA is here to assist you in this exciting field. All
astronomers, both amateur and professional, can make occultation observations.
This book has all the necessary information one needs to begin a successful
occultation program. Whether you are a novice observer, or an advanced observer
with a video system, you can assist in the search for asteroidal moons, help
discover new double stars and help determine the size of the Sun during solar
eclipses.
Written
by IOTA’s most experienced astronomers, this is the only book you’ll need for
occultation observations of stars by the Moon, by asteroids, and other solar
system bodies. It includes an extensive set of Appendices, and over 120 figures
and diagrams, 388 pages. Chasing the Shadow: The IOTA Occultation Observer’s
Manual is currently online FOR
FREE as an e-book.

IOTA WANTS YOU!!
The International Occultation Timing Association is a scientific organization dedicated to promoting the observation, prediction and analysis of lunar and asteroid occultations and solar eclipses. Toward this purpose, IOTA astronomers have organized teams of observers worldwide to travel to observe grazing occultations of stars by the Moon, eclipses of stars by asteroids and solar eclipses since 1962.
