Introduction
The
Partial Lunar Eclipse of 1854 Nov 04
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.

see Key to Lunar Eclipse Figures.
The instant of greatest eclipse takes place on 1854 Nov 04 at 21:12:49 TD (21:12:41 UT1).
This is 6.3 days before the Moon reaches apogee.
During the eclipse, the Moon is in the constellation Aries.
The synodic month in which the eclipse takes place has a Brown Lunation Number of -843.
The eclipse belongs to Saros 114 and is number 50 of 71 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 is a very shallow partial eclipse.
It has an umbral eclipse magnitude of only 0.0538 and a partial eclipse duration of 54.3 minutes.
Gamma has a value of -0.9707.
The partial lunar eclipse of 1854 Nov 04 is followed two weeks later by a hybrid solar eclipse on 1854 Nov 20.
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
7.1
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 = 21.000

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 Lunar Eclipse of 1854 Nov 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
7.1
seconds for this eclipse.
