Introduction

The Total Lunar Eclipse of 2091 Mar 05 is visible from the following geographic regions:

  • Europe, eastern Africa, Asia, Australia, western North America

The diagram to the right depicts the Moon's path with respect to Earth's umbral and penumbral shadows. Below it is a map showing the geographic regions of eclipse visibility.

The instant of greatest eclipse takes place on 2091 Mar 05 at 15:58:22 TD (15:56:24 UT1). This is 1.0 days before the Moon reaches perigee. During the eclipse, the Moon is in the constellation Leo. The synodic month in which the eclipse takes place has a Brown Lunation Number of 2080.

The eclipse belongs to Saros 134 and is number 31 of 72 eclipses in the series. All eclipses in this series occur at the Moon’s ascending node. The Moon moves southward with respect to the node with each succeeding eclipse in the series and gamma decreases.

The total lunar eclipse of 2091 Mar 05 is preceded two weeks earlier by a partial solar eclipse on 2091 Feb 18.

These eclipses all take place during a single eclipse season.

The eclipse predictions are given in both Terrestrial Dynamical Time (TD) and Universal Time (UT1). The parameter ΔT is used to convert between these two times (i.e., TD = UT1 + ΔT). ΔT has a value of 118.2 seconds for this eclipse.

The following links provide maps and data for the eclipse.

At time t1 (decimal hours), each besselian element is evaluated by:

x = x0 + x1*t + x2*t2 + x3*t3 (or x = Σ [xn*tn]; n = 0 to 3)

Eclipse Predictions

Predictions for the Total Lunar Eclipse of 2091 Mar 05 were generated using the JPL DE430 solar and lunar ephemerides. The lunar coordinates were calculated with respect to the Moon's Center of Mass.

The Earth's umbral and penumbral shadows were calculated using the Danjon methodusing a mean mid-latitude ellipticity to compensate for the opacity of the terrestrial atmosphere.

The predictions are given in both Terrestrial Dynamical Time (TD) and Universal Time (UT1). The parameter ΔT is used to convert between these two times (i.e., UT1 = TD - ΔT). ΔT has a value of 118.2 seconds for this eclipse.
