Leo 2.2° · born July 25, 1920
Birth time unknown

Birth date sourced. Birth time unknown.Moon sign undetermined. The Moon crossed from Scorpio into Sagittarius during that day. Everything below uses only what the complete civil day settles.

The day, read honestly

Five of the nine placements whose signs are settled stand in Leo — the Sun, Mercury, Venus, Jupiter and Neptune. 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 Notting Hill—a reference instant, not a birth time. No houses, rising sign, angles, or sect were computed.

Where the Sun actually stood

The Sun sits at 2.2° Leo — the first decan, 0°–10°, which the tradition sub-rules by the Sun. Degrees matter more than the sign label here: two people born a fortnight apart share Leo and share almost nothing else about where the Sun actually stood.

The angles that hold

The tightest geometry in the chart puts Mercury at right angles from Mars, 1.2° off exact. A square is friction that produces motion — the aspect the tradition credits with building capability precisely by refusing to be comfortable. Behind it, Mars trine Pluto at 1.4°, and Mars trine Uranus at 1.6° — both still well inside the orbs this site uses. These angles were checked through every hour of that civil day and survive throughout, which is why an unrecorded hour does not disturb them.

The classical map

The dignity table, which predates the outer planets and only ever spoke for seven, marks two placements here. The Sun in Leo at 2.2° is in domicile — the planet in its own sign, running on home rules; Mars in Scorpio at 6.5° is in domicile. None of these labels is a verdict on a person; they describe how a function is situated, nothing more.

The shape of the whole

The honest balance sheet uses the 9 placements whose signs hold for the whole day: fire 5, water 3, earth 1 across the elements, and fixed 6, mutable 2, cardinal 1 across the modalities. A fire emphasis is read as appetite for the first move, with information gathered by doing rather than before doing. No settled placement falls in air — an absence the tradition treats as information, not as a defect. Mercury and Uranus were retrograde — motion that reverses only from this vantage point, and which the old reading treats as delay used for revision.

The Moon is genuinely open

The Moon crossed from Scorpio into Sagittarius during that day at the birthplace, travelling 11.9° between one midnight and the next. Which of the two it was depends entirely on the hour, and the hour is not recorded. Rather than pick the likelier half, the reading leaves the Moon open.
