"Eclipse Predictions by Fred Espenak, NASA/GSFC"
Key to Catalog of Lunar Eclipses
Column Heading Definition/Description
1 Date Calendar Date (Gregorian) at instant of
(Julian calendar is used before 1582 Oct 15).
2 Greatest Universal Time (UT) of Greatest Eclipse, which is
Eclipse defined as the instant when Moon passes closest
to the axis of Earth's shadows.
3 Type Type of lunar eclipse where:
N = Penumbral Eclipse.
P = Partial (Umbral) Eclipse.
T = Total (Umbral) Eclipse.
(Tc = central total eclipse)
If the Type ends with:
"m" = Middle eclipse of Saros series.
"+" = Central eclipse (Moon north of axis).
"-" = Central eclipse (Moon south of axis).
"b" = Saros series begins (first eclipse in series).
"e" = Saros series ends (last eclipse in series).
4 Saros Saros series of eclipse.
(Each eclipse in a Saros is separated by an interval
of 18 years 11.3 days.)
5 Gamma Distance of the Moon from the axis of Earth's
shadow cone (units of equatorial radii) at the
instant of greatest eclipse.
6 Pen. Penumbral eclipse magnitude is the fraction of
Mag. the Moon's diameter obscured by the penumbra.
7 Umb. Umbral eclipse magnitude is the fraction of
Mag. the Moon's diameter obscured by the umbra.
8 S.D. Semi-duration of partial (umbral) eclipse (minutes).
9 S.D. Semi-duration of total (umbral) eclipse (minutes).
10 GST0 Greenwich Siderial Time at 00:00 U.T..
11 Moon Geocentric Right Ascension of the Moon
RA at greatest eclipse (hours).
12 Moon Geocentric Declination of the Moon
Dec at greatest eclipse (degrees).
