Birth time unknown

Birth date sourced. Birth time unknown.The Moon remained in Aries throughout that civil day. Everything below uses only what the complete civil day settles.

The day, read honestly

The Sun stands at 11.6° Leo, in domicile — the planet in its own sign, running on home rules. Of everything the chart can be read for without a birth time, that is the loudest single fact in it.

Positions at 12:00 civil time in New Orleans—a reference instant, not a birth time. No houses, rising sign, angles, or sect were computed.

Where the Sun actually stood

At the noon reference the Sun sits 11.6° into Leo — the second decan, which the old scheme hands to Jupiter. Same sign, different decan, different chart.

The fast planets

The personal planets sit Mercury at 22.5° Cancer, Venus at 7.2° Virgo, Mars at 12.9° Libra. Mercury in a water sign reads as thought steeped in tone and memory; Venus in a earth sign reads as attraction that grows by reliability; Mars in a air sign reads as effort aimed through strategy and words.

The angles that hold

The day's firmest angle joins Mars and Uranus — a sextile holding at 0.1°. A sextile pays out only on effort; the scheme calls it opportunity rather than gift. Behind it, the Sun sextile Mars at 1.3°, and the Sun trine Uranus at 1.4° — both still well inside the orbs this site uses. The unknown hour cannot unmake any of this: every aspect named survived all twenty-five samples of the day.

The standing structure

The Moon makes no major aspect that survives the day; the old reading gives such a planet autonomy — it acts alone, sometimes loudly.

The classical map

The oldest layer of the scheme — seven planets, four conditions — flags five placements in this chart. The Sun in Leo at 11.6° is in domicile — the planet in its own sign, running on home rules; Venus in Virgo at 7.2° is in fall — the tradition’s uphill placement, strength earned rather than given; Mars in Libra at 12.9° is in detriment — the planet opposite its home, working against the grain; Jupiter in Capricorn at 4.3° is in fall; Saturn in Capricorn at 11.1° is in domicile. The table describes circumstance rather than quality — a planet in detriment is inconvenienced, not diminished.

The shape of the whole

Tallied where the signs are certain — 10 placements whose signs hold for the whole day — the chart gives fire 3, earth 3, water 2, air 2, and cardinal 6, mutable 3, fixed 1 across the modes. Jupiter, Saturn and Uranus were retrograde — apparent backward motion from where the Earth sits, which the tradition reads as a function turned inward before it is turned out.

The Moon, and how far it can move

The Moon stayed in Aries for the whole of that day at the birthplace, covering 14.2° between midnight and midnight. That is quick enough to make the exact degree a neighbourhood rather than an address, and slow enough to leave the sign settled. At the noon reference it stands at 7.5°.
