Total Eclipse in Europe on August 11, 1999

Fred Espenak of NASA has much of the information on his Reference Publication on the Web.

This eclipse path passes through Europe, the Middle East and India. He has lots of maps, tables, weather prospects and other info posted. There are also instructions for ordering the new NASA bulletin on this eclipse.

Eclipse Reports from the British Astronomical Association

Reports on the recent solar eclipse from Mongolia as well as other sites are available from the British Astronomical Association's website.

Eclipse of March 9, 1997

My own site, in Darhan, Mongolia, was largely cloudy.

Sites farther north and east along the path, in China and Siberia, were clear. Here is the report from Daniel Fischer.

Reports from China, Mongolia, and Siberia are available from the British Astronomical Association.

Sky and Telescope Eclipse Reports

Sky and Telescope's site is keeping up with eclipse reports.

Planetary Photojournal

A wide variety of planetary photographs are available for purchase from a joint Web page set up by NASA's Jet Propulsion Laboratory and the U.S. Geological Survey.

October Partial Solar Eclipse Pages

A page describing Prof. Pasachoff's observations of the October 12 partial solar eclipse from Jerusalem is now available. There is also a page devoted to European Southern Observatory student studies of the eclipse.

Views of the Solar System

Views of the Solar System has been created by Calvin J. Hamilton at the Los Alamos National Laboratory as an educational tour of the solar system. It contains images and information about the Sun, planets, moons, asteroids, comets and meteoroids found within the solar system. It contains over 220 pages of information, over 950 high-resolution images and animations, and over 880 megabytes of data. The image processing for many of the images was done by the author.

Lots of Space News (November 5)

David Kropp of Michigan keeps lots of articles and releases about the solar system on line.

Planetary Science Research Discoveries (October 28)

A site with the latest research discoveries in planetary sciences is maintained by the Hawaii Institute of Geophysics of the University of Hawaii.

Solar Eclipse Homepage (September 19)

Fred Espenak of the NASA Goddard Space Flight Center has a homepage devoted to eclipses, with lots of his own calculations and lots of hotlinks.

Tour of the Solar System (June 10)

See the tour of the solar system put together by Calvin J. Hamilton and maintained at the Los Alamos National Laboratory.

Solar System Site on WWW (May 20)

A very nice site including all kinds of information about the sun, including descriptions and photographs of many types of solar phenomena, is available on the World Wide Web. It was assembled by Bill Arnett of San Jose, CA, as part of his Nine Planets site.

  • Pasachoff Observes Total Eclipses in 1994 and 1995

    (related to p. 119, Section 6.3c: Observing Solar Eclipses) Since the 1991 expedition described, total solar eclipses were observed in South America on November 3, 1994, and southeast Asia on October 24, 1995. On both occasions, clear weather existed along most of the path. My group's observations from Rajasthan, India, were updated versions of those to study the heating of the solar corona discussed on p. 121. On October 24, in India, Dr. Arvind Bhatnagar of the Udaipur Solar Observatory supervised a MiG-25 aircraft flying at 80,000 feet altitude to photograph the outer solar corona in the darkest, clearest possible sky. The copilot took direct and polarization images. A second aircraft, a Canberra, flew at 40,000 feet with the same apparatus. Both planes belong to the Indian Air Force. The eclipse began in Iran; the path of totality crossed Pakistan, India, Myanmar, Thailand, Cambodia, and Vietnam. A giant public education program in India convinced many citizens that it was not harmful to be outside during the eclipse, overcoming superstition.

    On October 12, 1995, a partial solar eclipse will be visible from Europe. The next two total eclipses will be on March 9, 1997, over Mongolia and Siberia, and on August 11, 1999, over Europe (ending in India).

    An eclipse homepage is available, as are photos. Select a thumbnail to download the full image.

    The photos are by Jay M. Pasachoff; Rana Nichols-Kiley assisted him in taking the second.

    Is a Jupiter required to form an Earth?

    Observations of molecular gas surrounding 20 stars in the million-to-10-million-year-old range found little gas. These stars had been seen by IRAF to contain a lot of dust, which acts as a shield to protect molecules. Ben Zuckerman of UCLA and colleagues, who made the observations with the 30-m radio telescope in Spain, have therefore proposed that gas must dissipate rapidly after a solar system is formed, making it necessary to form planets like Jupiter very early. The Earth, by contrast, is thought to have taken 100 million years to accumulate. The observations bear on the question whether it is necessary to have a large, Jupiter-like, object in the solar system in order to form an Earth.
