Introduction
The Partial Lunar Eclipse of 1903 Apr 12 is visible from the following geographic regions:
- Americas, Europe, Africa, western Asia. western Australia
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 1903 Apr 12 at 00:12:59 TD (00:12:58 UT1). This is 6.2 days after the Moon reaches perigee. During the eclipse, the Moon is in the constellation Virgo. The synodic month in which the eclipse takes place has a Brown Lunation Number of -244.
The eclipse belongs to Saros 130 and is number 28 of 71 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 is a very deep partial eclipse. It has an umbral eclipse magnitude of 0.9677 and a partial eclipse duration of 196.6 minutes. Gamma has a value of 0.4798.
The partial lunar eclipse of 1903 Apr 12 is preceded two weeks earlier by a annular solar eclipse on 1903 Mar 29.
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 1.6 seconds for this eclipse.
