Introduction

eclipse map

The Partial Solar Eclipse of 1345 Mar 04 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 1345 Mar 04 at 22:47:12 TD (22:40:30 UT1). This is 5.3 days before the Moon reaches perigee. During the eclipse, the Sun is in the constellation Pisces. The synodic month in which the eclipse takes place has a Brown Lunation Number of -7146.

The eclipse belongs to Saros 90 and is number 83 of 83 eclipses in the series. Thus, the 1345 Mar 04 event is the last eclipse of 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 is an extremely shallow partial eclipse. It has an eclipse magnitude of only 0.0326, while Gamma has a value of 1.5306. This is a very deep partial eclipse. It has an eclipse magnitude of 0.0326, while Gamma has a value of 1.5306.

The partial solar eclipse of 1345 Mar 04 is followed two weeks later by a total lunar eclipse on 1345 Mar 18.

Another solar eclipse occurs one synodic month after the 1345 Mar 04 eclipse. It is the partial solar eclipse of 1345 Apr 03.

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 401.9 seconds for this eclipse.

The following links provide maps and data for the eclipse.

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 = 23.000

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 Partial Solar Eclipse of 1345 Mar 04 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 401.9 seconds for this eclipse.
