NASA Solar Eclipse Bulletins

Annular and Total Solar Eclipses of 2010 (NASA/TP-2008-214171)

Two central eclipses of the Sun occur during 2010. The first is an annular solar eclipse on January 15 and is visible from a broad track across Africa, the Indian Ocean and south Asia. The second is a total solar eclipse on July 11 and is visible from a corridor that traverses the South Pacific.

Annular and Total Solar Eclipses of 2010 (NASA/TP-2008-214171) contains detailed predictions for both of these events and includes Besselian elements, geographic coordinates of the paths of annulatity and totality, physical ephemeris of the antumbra and umbra, topocentric limb profile corrections, local circumstances for hundreds of cities, maps of the eclipse paths, weather prospects, and lunar limb profile figures. Information on safe eclipse viewing and eclipse photography is also 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.
