Introduction
The Annular Solar Eclipse of 2270 Jul 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 2270 Jul 18 at 22:59:54 TD (22:52:55 UT1). This is 0.5 days after the Moon reaches apogee. During the eclipse, the Sun is in the constellation Gemini. The synodic month in which the eclipse takes place has a Brown Lunation Number of 4299.
The eclipse belongs to Saros 150 and is number 31 of 71 eclipses in the series. All eclipses in this series occur at the Moons descending node. The Moon moves northward with respect to the node with each succeeding eclipse in the series and gamma increases.
The solar eclipse of 2270 Jul 18 is a relatively long annular eclipse with a duration at greatest eclipse of 06m57s. It has an eclipse magnitude of 0.9474.
The annular solar eclipse of 2270 Jul 18 is preceded two weeks earlier by a partial lunar eclipse on 2270 Jul 04.
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 418.8 seconds for this eclipse. The uncertainty in ΔT is 108.9 seconds corresponding to a standard error in longitude of the eclipse path of ± 0.45°.
