Cancer 1.6° · born June 23, 1912
Birth time unknown

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

The day, read honestly

Tightest of all, Venus holds a conjunction to Pluto at 0.4° — close enough to weld taste to depth. A conjunction is the least negotiable aspect in the scheme — no distance to argue across, so the pair arrives as a single instinct.

Positions at 12:00 civil time in Maida Vale—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 1.6° into Cancer — the first decan, which the old scheme hands to the Moon. Same sign, different decan, different chart.

The personal registers

Mercury holds 8.9° Cancer, Venus holds 28.1° Gemini, Mars holds 15.6° Leo — in the old shorthand, thought steeped in tone and memory; attraction that begins as conversation; effort spent in bursts and openings.

The angles that hold

Start where the chart is tightest — Venus conjunction Pluto, 0.4° of separation. A conjunction is the least negotiable aspect in the scheme — no distance to argue across, so the pair arrives as a single instinct. Behind it, the Sun conjunction Pluto at 3.0°, and the Sun conjunction Venus at 3.5° — both still well inside the orbs this site uses. Every angle named here holds for the whole of that day at the birthplace, so an unknown hour cannot take it away.

The standing structure

Mars 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 dignity table, which predates the outer planets and only ever spoke for seven, marks one placement here. Jupiter in Sagittarius at 7.9° is in domicile — the planet in its own sign, running on home rules. The table describes circumstance rather than quality — a planet in detriment is inconvenienced, not diminished.

The shape of the whole

Counting only the 10 placements whose signs hold for the whole day, the chart runs 4 air, 3 water, 2 fire, 1 earth by element and 4 cardinal, 3 mutable, 3 fixed by modality. Jupiter and Uranus 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 Libra for the whole of that day at the birthplace, covering 13.1° between midnight and midnight. Fast enough that its degree is approximate, slow enough that its sign is not in doubt. At the noon reference it stands at 21.9°.
