Introduction

The Total Lunar Eclipse of -1552 Jun 05 (1553 Jun 05 BCE) is visible from the geographic regions shown on the map to the right. The diagram above the map depicts the Moon's path with respect to Earth's umbral and penumbral shadows. Click on the figure to enlarge it. For an explanation of the features appearing in the figure, see Key to Lunar Eclipse Figures.

The instant of greatest eclipse takes place on -1552 Jun 05 at 01:13:35 TD (15:10:54 UT1). This is 1.5 days before the Moon reaches perigee. During the eclipse, the Moon is in the constellation Sagittarius. The synodic month in which the eclipse takes place has a Brown Lunation Number of -42975.

The eclipse belongs to Saros 15 and is number 38 of 73 eclipses in the series. All eclipses in this series occur at the Moon’s descending node. The Moon moves northward with respect to the node with each succeeding eclipse in the series and gamma increases.

This total eclipse is central meaning the Moon’s disk actually passes through the axis of Earth’s umbral shadow. It has an umbral eclipse magnitude of 1.8341, and Gamma has a value of 0.0256. Because they are so deep, such eclipses typically have the longest total phases. In this case, the duration of totality lasts 100.2 minutes. That qualifies the eclipse as a member of a select class of exceptionally long total eclipses with durations exceeding 100 minutes.

The total lunar eclipse of -1552 Jun 05 is preceded two weeks earlier by a partial solar eclipse on -1552 May 20, and it is followed two weeks later by a partial solar eclipse on -1552 Jun 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 36161.1 seconds for this eclipse. The uncertainty in ΔT is 2064.0 seconds corresponding to a standard error in longitude of the eclipse visibility zones of 8.62°.

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 = 1.000

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 Lunar Eclipse of -1552 Jun 05 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 36161.1 seconds for this eclipse. The uncertainty in ΔT is 2064.0 seconds corresponding to a standard error in longitude of the eclipse visibility zones of 8.62°.
