mysteries of egyptian zodiacs - HiddenMysteries Information Central

Later, in the subsequent chapters, we will present the
checkup tables for all the ideal solutions of the specific Egyptian
zodiacs. In this tables we will use the following abbreviations:
1. SUH — the submersion of the Sun under the local horizon
measured in degrees. For example SUH=10 o means
that the submersion of the Sun was 10 o .
• The submersion of the Sun is measured at the moment
when a planet is raising or setting down over
the local horizon (depending on the morning, or respectively,
the evening visibility of this planet that is
examined). At that moment, if the submersion of the
Sun is sufficient, it is possible for an observer to see
the planet on the sky. We will always assume that all
the submersions of the Sun are calculated for an observer
located in Cairo, except the cases when it will
be specified otherwise. Let us recall that a planet with
an average brightness is visible if the submersion of
the Sun is 10 o or more, and a bright planet (with the
magnitude M = −3.5) is visible if the submersion of
the Sun is about 7 o –8 o , or more (see section 6.7, Step
3 [B]).
2. M — the magnitude of brightness of the planet measured
according to the photometric scale. For example M =
−3.2 means that at that moment the brightness of the
planet was −3.5. As we explained before, brightness of
the planets changes with time.
• Let us recall that the brightness according to the photometric
scale can be possibly expressed by negative
numbers — smaller the number, higher the brightness
of the planet. The brightest planet is Venus. Its
magnitude can reach up to M = −4, but the most
frequently it is from M = −3 to M = −3.7. The
magnitude from M = 0 to M = +1 is characteristic
not only for the planets but also for bright stars. The
planets with such magnitude of brightness are visible
on the sky only when it is sufficiently dark. Such conditions
exist if the submersion of the Sun is at least
8 o –9 o . Less bright planets can be observed with the
naked eye only if the submersion of the Sun is 10 o or
more. With the submersion of the Sun of 18 o , there
is a complete darkness. At that time it is possible to
see faint stars. We discussed this issue in subsection
6.7.3.
3. Decimal Number from 0 to 12 in brackets, indicating
a position of the planet according to the constellationsized
scale (see section 6.10). For example, (2.5) denotes
the middle of Gemini, or a point with the longitude 70 o
on the ecliptic J2000, and (0.2) – a point in Aries with
longitude 31 o on the ecliptic J2000 (see section 6.10).
4. Sometimes, in a column related to the visibility conditions
of a certain planet, we indicate its distance (in degrees)
from the Sun, which we denote using the capital Greek
letter delta: ∆.
We use the last column in the checkup table for comments.
At the bottom of this column we placed a sequence of squared
6.14 Check-up List for an Astronomical Solution 147
boxes, corresponding to the columns in the table. Each of
these boxes contains one of the signs +, − or ±, depending
on how the solutions agrees with the zodiac. If the solution is
complete, in all boxes there are only plus signs. In addition
to these boxes, we also included there the mean discrepancy
from the best points for this solution, which we denoted by
the symbol ∆av (see section 6.11).
