Total Solar Eclipse of 2009 July 22

On Wednesday, 2009 July 22, a total eclipse of the Sun is visible from within a narrow corridor that traverses half of Earth. The path of the Moon's umbral shadow begins in India and crosses through Nepal, Bangladesh, Bhutan, Myanmar and China. After leaving mainland Asia, the path crosses Japan's Ryukyu Islands and curves southeast through the Pacific Ocean where the maximum duration of totality reaches 6 min 39 s. 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.

This web site has been established for the purpose of providing detailed predictions, maps, figures and information about this important event. The material here is adapted from the NASA Technical Publication "Total Solar Eclipse of 2009 July 22" (NASA/TP-2008-214169). The document will be published in 2008 March. It is part of NASA's official eclipse bulletin publication series. Instructions and a form for ordering a hard copy of this publication can be found at: Order Form for NASA Eclipse Bulletins.


Preliminary Look at the Total Solar Eclipse of 2009 Jul 22

Interactive Map of the Path of Totality

An implementation of Google Map has been created which includes the central path of the 2009 total solar eclipse. This allows the user to select any portion of the path and to zoom in using either map data or Earth satellite data.


General Maps of the Eclipse Path

The following maps show the overall regions of visibility of the partial eclipse as well as the path of the total eclipse through Asia and the Pacific Ocean. They use high resolution coastline data from the World Data Base II (WDB). Each map was chosen to isolate a specific region along the land portion of the eclipse path. Curves of maximum eclipse are included as well as the outline of the umbral shadow.

The maps are available as high resolution (300 dpi) PDF files.

Detailed Maps of the Path of Totality

The following maps show path of the 2009 total eclipse in greater detail. They use high resolution coastline, city and highway data from the Digital Chart of the World (DCW). Each map was chosen to isolate a specific region along the land portion of the eclipse path. Curves of maximum eclipse are included as well as the outline of the umbral shadow. Within the umbral path, curves of constant duration have been plotted for totality.

The maps are available as high resolution (300 dpi) PDF files.

Eclipse Elements, Shadow Contacts and Path of Totality

The following tables give detailed predictions including the Besselian Elements, shadow contacts with Earth, path of the umbral shadow and topocentric data (with path corrections) along the path. Also included are special extended version tables of path coordinates and graze zones in formats convenient for plotting on maps.

From NASA Tech. Pub. "Total Solar Eclipse of 2009 July 22" (NASA/TP-2008-214169).


Local Circumstances

The following tables give the local circumstances of the eclipse from various cities throughout Asia and the Pacific Ocean. All contact times are given in the tables are in Universal Time.
