Introduction
The
Partial Solar Eclipse of -1906 Jan 07 (1907 Jan 07 BCE)
is visible from the geographic regions shown on the map to the right.

see Key to Solar Eclipse Maps.
The instant of greatest eclipse takes place on -1906 Jan 07 at 14:36:19 TD (02:20:10 UT1).
This is 0.6 days after the Moon reaches perigee.
During the eclipse, the Sun is in the constellation Capricornus.
The synodic month in which the eclipse takes place has a Brown Lunation Number of -47358.
The eclipse belongs to Saros 30 and is number 9 of 83 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 is a very deep partial eclipse.
It has an eclipse magnitude of 0.0910,
while Gamma has a value of -1.4866.
The partial solar eclipse of -1906 Jan 07 is preceded two weeks earlier by a total lunar eclipse on -1907 Dec 23.
Another solar eclipse occurs one synodic month before the -1906 Jan 07 eclipse. It is the partial solar eclipse of -1907 Dec 09.
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
44169.2
seconds for this eclipse.
The uncertainty in ΔT is
3346.5 seconds corresponding to a standard error in longitude of the eclipse path of ± 13.98°.

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 = 15.000

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 -1906 Jan 07
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
44169.2
seconds for this eclipse.
The uncertainty in ΔT is
3346.5 seconds corresponding to a standard error in longitude of the eclipse path of ± 13.98°.
