Lunar Eclipses: 1921 - 1930
Fred Espenak
Introduction
A concise summary of all lunar eclipses from 1921 through 1930 is presented here in two ways. The first is a series of Figures showing the Moon's path through Earths shadows for each eclipse. The second is a Table listing the primary characteristics of each eclipse. Near the bottom of the page are a series of Links to more on lunar eclipses.
Figures of Lunar Eclipses: 1921 - 1930
The figures below offer a concise summary of all lunar eclipses from 1921 through 1930 . Each figure consists of a diagram showing the Moon's path through Earth's shadows and a map depicting the geographic region of visibility for a single eclipse. Click on an eclipse figure to link to a web page with complete details about that eclipse, including a larger version of the figure. Visit the Key to Lunar Eclipse Figures for a detailed explanation of these figures.
Table of Lunar Eclipses: 1921 through 1930
A concise summary of all lunar eclipses from 1921 through 1930 is presented in the table below. The first column gives the Calendar Date of the instant of greatest eclipse. The second column TD of Greatest Eclipse is the Terrestrial Dynamical Time (TD) when the Moon passes closest to the axis Earth's shadow. The third column lists the Eclipse Type which is either Total, Partial, or Penumbral.
Eclipses recur over the Saros cycle, a period of approximately 18 years 11 days. Each eclipse belongs to the Saros Series shown in column 4. The Umbral Magnitude gives the fraction of the Moon's diameter immersed in Earth's umbral shadow at the instant of greatest eclipse (column 5). The Eclipse Duration gives the length of the partial eclipse. 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 (column 6). Finally, the Geographic Region of Eclipse Visibility provides a brief description of where each eclipse will be seen.
The eclipse date (first column) links to the prime page for the eclipse. This page features an eclipse diagram and map showing the geographic region of eclipse visibility, as well as detailed predictions, Besellian elements and links to additional information about the eclipse.
The Key to Lunar Eclipse Decade Table contains a more detailed description of each item in the table.

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.
