Introduction
The Total Lunar Eclipse of 1909 Nov 27 is visible from the following geographic regions:
- eastern Asia, Australia, Americas, western Europe, western Africa
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 1909 Nov 27 at 08:54:41 TD (08:54:30 UT1). This is 1.8 days after the Moon reaches perigee. During the eclipse, the Moon is in the constellation Taurus. The synodic month in which the eclipse takes place has a Brown Lunation Number of -162.
The eclipse belongs to Saros 124 and is number 43 of 73 eclipses in the series. All eclipses in this series occur at the Moons ascending node. The Moon moves southward with respect to the node with each succeeding eclipse in the series and gamma decreases.
This total eclipse is central meaning the Moons disk actually passes through the axis of Earths umbral shadow. It has an umbral eclipse magnitude of 1.3660, and Gamma has a value of -0.2713. Because they are so deep, such eclipses typically have the longest total phases. In this case, the duration of totality lasts 81.2 minutes.
The total lunar eclipse of 1909 Nov 27 is followed two weeks later by a partial solar eclipse on 1909 Dec 12.
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 10.2 seconds for this eclipse.
