Introduction
The
Total Solar Eclipse of -1462 Feb 17 (1463 Feb 17 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 -1462 Feb 17 at 07:27:08 TD (21:56:07 UT1).
This is 0.5 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 -41865.
The eclipse belongs to Saros 36 and is number 23 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 very unusual in that it is NON-CENTRAL and does NOT have a central line nor a southern path limit.
Instead , over half of the umbral shadow falls off into space throughout the eclipse.
Gamma has a value of -0.9982.
The total solar eclipse of -1462 Feb 17 is preceded two weeks earlier by a total lunar eclipse on -1462 Feb 02.
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
34261.1
seconds for this eclipse.
The uncertainty in ΔT is
1782.7 seconds corresponding to a standard error in longitude of the eclipse path of ± 7.45°.
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 = 7.000

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 -1462 Feb 17
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
34261.1
seconds for this eclipse.
The uncertainty in ΔT is
1782.7 seconds corresponding to a standard error in longitude of the eclipse path of ± 7.45°.
