Introduction
The Total Solar Eclipse of 1749 Jan 18 is visible from the geographic regions shown on the map to the right. Click on the map to enlarge it. For an explanation of the features appearing in the map, see Key to Solar Eclipse Maps.
The instant of greatest eclipse takes place on 1749 Jan 18 at 19:08:56 TD (19:08:43 UT1). This is 0.5 days before the Moon reaches perigee. During the eclipse, the Sun is in the constellation Capricornus. The synodic month in which the eclipse takes place has a Brown Lunation Number of -2151.
The eclipse belongs to Saros 127 and is number 43 of 82 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.
The solar eclipse of 1749 Jan 18 is a relatively long total eclipse with a duration at greatest eclipse of 04m07s. It has an eclipse magnitude of 1.0465.
The total solar eclipse of 1749 Jan 18 is preceded two weeks earlier by a penumbral lunar eclipse on 1749 Jan 03, and it is followed two weeks later by a penumbral lunar eclipse on 1749 Feb 02.
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., UT1 = TD - ΔT). ΔT has a value of 12.6 seconds for this eclipse.
