NASA Solar Eclipse Bulletins

Total Solar Eclipse of 2009 July 22 (NASA/TP-2008-214169)

On 2009 July 22, a total eclipse of the Sun is visible from within a narrow corridor that traverses half the Earth. The path of the Moon's umbral shadow begins in India and crosses through Nepal, Bangladesh, Bhutan and China before curving south across the Pacific Ocean. A partial eclipse is seen within the much broader path of the Moon's penumbral shadow, which includes most of eastern Asia, Indonesia, and the Pacific Ocean.

Total Solar Eclipse of 2009 July 22 (NASA/TP-2008-214169) contains detailed predictions for this event and includes Besselian elements, geographic coordinates of the path of totality, physical ephemeris of the umbra, topocentric limb profile corrections, local circumstances for about 250 cities, maps of the eclipse path, weather prospects, the lunar limb profile and the sky during totality. Information on safe eclipse viewing and eclipse photography is included.

NASA Eclipse Bulletins contain detailed predictions, maps and meteorology for future central solar eclipses of interest. These publications are prepared in cooperation with the Working Group on Eclipses of the International Astronomical Union and are provided as a public service to both the professional and lay communities, including educators and the media. In order to allow a reasonable lead time for planning purposes, subsequent bulletins will be published 18 to 24 months before each event.
