Lunar Eclipses: 2031 - 2040

Fred Espenak

A concise summary of all lunar eclipses from 2031 through 2040 is presented in the table below. The first column gives the Calendar Date of the instant of greatest eclipse[1]. The second column TD of Greatest Eclipse is the Terrestrial Dynamical Time of greatest eclipse. 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 the 4th column. The Umbral Magnitude[2] (column 5) gives the fraction of the Moon's diameter immersed in Earth's umbral shadow at the instant of greatest eclipse. The Eclipse Duration[3] 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. Finally, the Geographic Region of Eclipse Visibility[4] provides a brief description of the regions where each eclipse will be seen.

Two fields in the summary table provide links to graphics and additional information for each eclipse. A figure consisting of a diagram and map for each eclipse may be seen by clicking on the Calendar Date. The top diagram shows the Moon's trajectory with respect to Earth's penumbral and umbral shadows. The equidistant cylindrical projection map below illustrates the geographpic region of visibility for each phase of the eclipse. These figures are described in greater detail in the Key to Lunar Eclipse Maps. Each figure is stored as a PDF file of about 110 kilobytes.

All eclipses belonging to a particular Saros Series are listed in a table linked through the Saros number.

The Key to Lunar Eclipse Decade Table contains a more detailed description of each item in the table.

[1] Greatest Eclipse is the instant when the distance between the axis of Earth's umbral shadow and the center of the Moon's disk reaches a minimum.

[2] Umbral magnitude is the fraction of the Moon's diameter obscured by Earth's umbral shadow at the instant of greatest eclipse. For total eclipses, the umbral magnitude is always greater than or equal to 1. For partial eclipses, the umbral magnitude is always greater than 0 and less than 1. For penumbral eclipses, the umbral magnitude is always negative (i.e., less than 0).

[3] Eclipse Duration is the duration of the partial phase of a partial eclipse. For total eclipses two values are given. The first is the period between the beginning and end of the partial phases, while the second value (in bold is the duration of the total phase.

[4] Geographic Region of Eclipse Visibility is the portion of Earth's surface where some portion of the eclipse can be seen.
