A concise summary of all lunar eclipses from 1931 through 1940 is presented in the following table. Diagrams and maps for each eclipse may be seen by clicking the eclipse's Date. This links to a figure showing the Moon's path through Earth's shadow(s) and a world map illustrating the region of visibility for that particular eclipse. These figures are described in greater detail in the Key to Lunar Eclipse Maps. Each figure is stored as a GIF file of about 60 kilobytes. The Eclipse Type (Penumbral, Partial or Total) is given followed by the number of the Saros series. Eclipses belonging to a given Saros series recur every 18 years 11 days. The Umbral Magnitude[1] (fourth column) gives the fraction of the Moon's diameter immersed in Earth's umbral shadow at the instant of greatest eclipse. The Eclipse Duration[2] gives the length of the partial eclipse. If the eclipse is total, then the duration of the total phase is also listed in bold. Finally, the Geographic Region of Eclipse Visibility[3] provides a brief description of the region where each eclipse will be seen.

[1] Umbral magnitude is the fraction of the Moon's diameter obscured by Earth's Umbra. For penumbral eclipses, the umbral magnitude is always less than 0. For partial eclipses, the umbral magnitude is always greater than 0 and less than 1. For total eclipses, the umbral magnitude is always greater than or equal to 1.
[2] Eclipse Duration is the duration of a partial eclipse. If the eclipse is total, the duration of totality is given in bold.
[3] Geographic Region of Eclipse Visibility is the portion of Earth's surface where a lunar eclipse can be seen.
Every link in the following table displays a page containing 10 years of lunar eclipses. Each eclipse has links to diagrams, maps and saros tables.
