Birth date sourced. Birth time unknown.The Moon remained in Virgo throughout that civil day. Everything below uses only what the complete civil day settles.
The day, read honestly
Four of the ten placements whose signs are settled stand in Sagittarius — the Sun, Mercury, Mars and Jupiter. The placements whose signs could change with an unknown hour are not counted. A cluster that size becomes the section the rest of the chart plays around.
Positions at 12:00 civil time in Los Angeles—a reference instant, not a birth time. No houses, rising sign, angles, or sect were computed.
Where the Sun actually stood
At noon on that date the Sun stood at 29.2° Sagittarius, inside the third decan (20°–30°), whose traditional sub-ruler is the Sun. The decan is the older, finer division — it is what the sign looks like once you stop rounding it to thirty degrees.
The personal registers
Mercury holds 10.3° Sagittarius, Venus holds 16.3° Scorpio, Mars holds 12.9° Sagittarius — in the old shorthand, thought that arrives already in motion; attraction that works by atmosphere; effort spent in bursts and openings.
The angles that hold
The tightest geometry in the chart puts Saturn a sixth of the circle apart from Neptune, 0.2° off exact. Sextiles are read as standing invitations — productive exactly as often as they are accepted. Behind it, Saturn trine Pluto at 2.1°, and Neptune sextile Pluto at 2.3° — both still well inside the orbs this site uses. All of it stands whatever the hour was: each angle was tested from midnight to midnight before it was written down.
Figures in the geometry
No closed figure — no grand trine, t-square, or grand cross — holds among the day-stable angles. The chart distributes its tension pair by pair rather than through one standing structure.
The classical map
The oldest layer of the scheme — seven planets, four conditions — flags four placements in this chart. Mercury in Sagittarius at 10.3° is in detriment — the planet opposite its home, working against the grain; Venus in Scorpio at 16.3° is in detriment; Jupiter in Sagittarius at 16.5° is in domicile — the planet in its own sign, running on home rules; Saturn in Capricorn at 8.3° is in domicile. None of this ranks anyone; dignity describes footing, and footing can be worked with.
The shape of the whole
Balance, counted honestly across the 10 placements whose signs hold for the whole day: elements fire 5, earth 3, water 2; modalities mutable 6, fixed 3, cardinal 1. No settled placement falls in air — an absence the tradition treats as information, not as a defect. Uranus and Pluto were retrograde — the backward drift a body appears to make as the Earth overtakes it, read in the scheme as a function that reviews before it releases.
The Moon, and how far it can move
The Moon stayed in Virgo for the whole of that day at the birthplace, covering 12.8° between midnight and midnight. The sign survives the missing hour; the degree does not, and is given as a reference rather than a fact. At the noon reference it stands at 13.5°.
