Notes on this chart

Two arcminutes is all Neptune covered on this birth day, 7°00′ Aquarius to 7°02′, and Uranus covered the same two, 21°53′ Aquarius to 21°55′. The Moon was in the sign with them and covered twelve degrees of it, 6°48′ Aquarius to 18°56′ Aquarius.

An unrecorded hour leaves the two slow ones exactly where they stand and puts the Moon anywhere along that stretch. Its conjunction with Neptune sits at 0°12′ at one end of the day and 11°55′ at the other, and it comes within 2°59′ of Uranus and no closer.

The Sun spent the day opposite the North Node. It came to exact somewhere inside those hours and stood no further off than 0°37′ at any of them. That axis is where eclipses happen, and neither end of it moves fast enough for a lost hour to matter.

Nothing else in this chart holds an Earth sign; Mercury has one to itself, running 3°58′ Capricorn to 5°33′ Capricorn.

How the planets sit with each other

Aspects are the working relationships in a chart, listed tightest first. A smaller orb is a stronger contact. Contacts marked "part of the day" depend on the unknown birth time.

Tension

Squares and oppositions: friction that makes the engine turn.

Sun opposition North Node 0.0–0.6° exact all day
Pluto square Black Moon Lilith 2.3–2.4°· all day
Mars square Saturn 2.6–3.4°· all day
Saturn square Black Moon Lilith 2.9–3.0° part of the day
Saturn opposition Pluto 5.2–5.4°· all day

Flow

Trines and sextiles: what runs easily, sometimes too easily.

Moon sextile Pluto 0.4–8.7° part of the day
Moon trine Saturn 0.4–8.7° part of the day
Jupiter trine Black Moon Lilith 0.7–0.9° exact all day
Venus sextile Uranus 0.7–1.9°· all day
Mercury sextile Mars 2.1–2.9°· all day
Moon sextile Venus 2.3–13.2° part of the day
Saturn trine Neptune 3.2–3.3°· all day
Sun sextile Uranus 4.6–5.6° part of the day
Mars trine Jupiter 4.7–5.6° part of the day

Fused

Conjunctions: planets standing so close they act as one.

Moon conjunction Neptune 0.2–11.9° part of the day
Moon conjunction Uranus 3.0–15.1° part of the day
Mercury conjunction Chiron 3.3–4.8° part of the day
Sun conjunction Chiron 3.3–4.2° part of the day
Venus conjunction Pluto 4.4–5.7°· all day
Sun conjunction Venus 6.3–6.5°· all day
Sun conjunction Mercury 7.5–8.1° part of the day
