Lunation Families or Moon Families
Moon Family
Moon
Families (also known as
Lunation Families) is a method developed by Dietrech J. Pessin
and described in her book Lunar Shados: The Lost Key to the Timing of
Eclipses. The
idea is that each lunation is part of a 'family'
of lunations - so for example, a New Moon is followed by a first quarter moon 9
months later where the Moon is
at (more or less) the same degree as the New Moon. 9 months after this,
there is a Full Moon where the Moon is
at the same degree as the New Moon (with the Sun at the opposite degree
to the New Moon). The final stage of the moon family is
the last quarter, where again, 9 months later, the Moon falls
at the same degree (more or less) as the originating New Moon. This
cycle is basically a repetition of a moon
family cycle
from one metonic cycle previously, and it will again be repeated 19
years hence in a further metonic cycle. Each family may
or may not include eclipses, and over time; eclipses phase in and out of
the moon family because
the nodal return cycle is not exactly the same as the metonic cycle.
Moon
Families do not require the base chart and can be calculated
based on the start date and location.
To calculate the
Moon Families, expand the List menu and
select the
Lunation Families... menu option there.
- Select the Start Date,
- Set the Location.
- Click OK.
The Lunation Families table will appear.
Additional Features____________________________________________
- Charts can be created directly from the Lunation Families
table by double-clicking on the desired date.
