Key to Lunar Eclipse Decade Tables

Fred Espenak

The following key gives detailed descriptions of each column in the Lunar Eclipse Decade Tables.

Column     Heading     Definition/Description
   1      Calendar     Calendar Date at instant of Greatest Eclipse. 
            Date       Gregorian Calendar is used for dates after 1582 Oct 15.  
                       Julian Calendar is used for dates before 1582 Oct 04.   

   2         TD of     Dynamical Time (TD) of Greatest Eclipse, the instant 
           Greatest    when the axis of the Moon's shadow cone passes closest
           Eclipse     to Earth's center.

   3       Eclipse     Eclipse Type of Total, Partial or Penumbral.

   4       Saros       Saros series number of eclipse.
           Series      (Each eclipse in a Saros is separated by an interval
                       of 18 years 11.3 days.)

   5        Umbral     Eclipse magnitude is the fraction of the Moon's 
          Magnitude    diameter obscured by Earth's umbral shadow

   6      Eclipse      Eclipse Duration gives the length of the partial eclipse. 
          Duration     If the eclipse is total then two durations are listed. 
                       The first is the interval between the beginning and end of the partial phases. The second value (in bold) is the duration the total phase (minutes and seconds).

   7     Geographic    Description of location where each eclipse is visible from.
         Region of 

   7     Links        [1] - Links to the primary page for the eclipse and contains 
                      detailed predictions and links to additional maps and data.

                      [2] - Links to a diagram of the Moon's path trough Earth's shadows along with a map of Earth showing the regions of visibility for the eclipse. For a detailed description of the figures see: Key to Lunar Eclipse Maps.

Decade Tables of Lunar Eclipses

Each link in the following table displays a page containing 10 years of lunar eclipses. Every eclipse has links to an eclipse diagram and map of geographic visibility, and a dedicated web page for that eclipse.

Eclipse Predictions

The eclipse predictions presented here were generated using the JPL DE406 solar and lunar ephemerides. The lunar coordinates have been calculated with respect to the Moon's Center of Mass.
