Introduction

eclipse map


The Total Solar Eclipse of -1461 Jul 03 (1462 Jul 03 BCE) 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 -1461 Jul 03 at 14:00:58 TD (04:30:26 UT1). This is 2.8 days after the Moon reaches perigee. During the eclipse, the Sun is in the constellation Cancer. The synodic month in which the eclipse takes place has a Brown Lunation Number of -41848.

The eclipse belongs to Saros 13 and is number 61 of 85 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.

This total eclipse is unsual in that it does NOT have a southern path limit. Instead, one edge of the umbral shadow falls off into space throughout the eclipse. Gamma has a value of -0.9912.

The total solar eclipse of -1461 Jul 03 is followed two weeks later by a total lunar eclipse on -1461 Jul 19.

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 34232.4 seconds for this eclipse. The uncertainty in ΔT is 1778.5 seconds corresponding to a standard error in longitude of the eclipse path of ± 7.43°.

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)

where: t = t1 - t0 (decimal hours) and t0 = 14.000

Calendar

The Gregorian calendar (also called the Western calendar) is internationally the most widely used civil calendar. It is named for Pope Gregory XIII, who introduced it in 1582. On this website, the Gregorian calendar is used for all calendar dates from 1582 Oct 15 onwards. Before that date, the Julian calendar is used. For more information on this topic, see Calendar Dates.

The Julian calendar does not include the year 0. Thus the year 1 BCE is followed by the year 1 CE (See: BCE/CE Dating Conventions). This is awkward for arithmetic calculations. Years in this catalog are numbered astronomically and include the year 0. Historians should note there is a difference of one year between astronomical dates and BCE dates. Thus, the astronomical year 0 corresponds to 1 BCE, and astronomical year -1 corresponds to 2 BCE, etc..

Eclipse Predictions

Predictions for the Total Solar Eclipse of -1461 Jul 03 were generated using the JPL DE406 solar and lunar ephemerides. The lunar coordinates were calculated with respect to the Moon's Center of Mass. 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 34232.4 seconds for this eclipse. The uncertainty in ΔT is 1778.5 seconds corresponding to a standard error in longitude of the eclipse path of ± 7.43°.
