What the chart says
Allan, according to the stars
Core essence
Allan feels everything, and it is the best and hardest thing about them. The core of Allan is imagination with a soft heart behind it: the daydream, the creative pull, the instinct that knows how someone is doing before they do. They absorb the mood of a room and give back something kinder. Their softness is not weakness, it is the whole point.
The vibe
Underneath, Allan cannot fully relax while anyone in the room is unhappy. The Moon in Libra feels through harmony and hates conflict in their own house. What Allan needs to feel safe is fairness, softness and a partner in the small decisions. They are at their best when someone else picks the restaurant and they get to enjoy it.
How Allan wants to be loved
Allan wants to be loved boldly. Venus in Aries falls fast, says so, and wants you to chase back. Grand gestures land, so does a fight followed by a proper make-up. What bores them is hesitation. Be direct, be a little brave about them, and keep the spark lit on purpose.
How Allan creates
How Allan makes things happen: they keep moving. A Yang Water day master is the river, curious, restless, going somewhere even when nobody knows where. Allan creates by exploring, by talking to everyone, by carrying ideas from one place to another. Hard to pin down, impossible to dam, and the best person to have on a long trip.
Instinct
Instinct: Allan is quick, clever and alert, a Rat year, and their gut reaction to a problem is to find the angle nobody has tried. Charming, resourceful, a little bit of a hoarder of good things and good people. The Wood year adds growth: ideals, ambition, a need to be getting somewhere.
Purpose
Purpose: Life Path 5 is the free spirit. Allan is here to explore, to change, to taste everything and report back. Adventure, variety and freedom are not distractions from their purpose, they are it. The lesson is choosing, sometimes, and staying.
Triggers
Triggers: being fenced in, and being lied to. Mars in Sagittarius fights loud, laughs it off, and is genuinely fine ten minutes later. Allan has boundless energy for anything with a horizon in it and none for the small print. Aim them at something far away and step back.

The quick version
Pisces Sun
Pisces SunDreams in full colour.
Allan McLeod Cormack's Sun was in Pisces for the whole of February 23, 1924, so no birth time is needed to settle it. Traditional Pisces readings associate the sign with imagination, empathy and permeable boundaries: absorbing the mood of a place and turning it into something. Astrologers describe it as the mutable water sign, traditionally ruled by Jupiter and in modern practice by Neptune. The corresponding tension is drift, described in the tradition as a difficulty telling one's own feelings from everyone else's.
Wood Rat
Wood RatFinds the shortcut every time.
Allan McLeod Cormack was born on February 23, 1924, which falls in a Wood Rat year of the Chinese calendar. Traditional Rat readings emphasise quickness, resourcefulness and an eye for the opening nobody else has noticed. The Chinese almanacs describe the Rat as the strategist of the cycle, first in the order because it saw the shortcut. The corresponding caution in the tradition is scatter: too many angles worked at once, and charm spent where patience was needed.
Life Path 5
Life Path 5Freedom over comfort, always.
Allan McLeod Cormack's birth date, February 23, 1924, reduces to Life Path 5 under the numerology method AsterNym uses. Traditional Life Path 5 readings associate the number with freedom, change and variety: movement, new experience and resistance to restrictive routine. Numerologists describe it as the path of the traveller, adaptable and restless. The corresponding tension is instability, with the caution that constant motion can become a way of avoiding commitment to any one direction.

Allan’s birth chart
Reference chart · birth time unknown
No documented birth time exists for Allan McLeod Cormack, so the positions below are checked across the whole birth date, not fixed at noon. The Moon ranges from 1° to 15° Libra depending on the hour. The wheel's houses are a solar chart, counted from the Sun's sign, because the Ascendant needs a time.
No birth time, so the houses are a solar chart: the Sun’s sign counts as house 1. A documented time would place them from the Ascendant instead.

Allan’s Chiron, Ceres, Eros, Hygiea and Lilith
Four minor bodies and the mean lunar apogee, placed in the same tropical zodiac as the planets above. None of these feed the chart signature, the rarity score or any ranking on this site: they are listed for readers who use them. Chiron, Ceres, Eros and Hygiea positions come from JPL Horizons; Black Moon Lilith is the mean apogee, the point most published Lilith tables use. The readings are the modern tradition’s, not AsterNym’s. Without a birth time the degree is the noon value and the day's movement is shown alongside it.
⚷ ChironAries 17°54′ (moves 0.05° over the day)
centaur (2060) · the wound and what is learnt from it
Chiron in Aries is read as a sore spot around asserting oneself: Allan may have learnt early that going first costs something, and built a way of leading that does not need permission.
⚳ CeresPisces 12°40′ (moves 0.39° over the day)
dwarf planet (1) · how a person nurtures and wants to be nurtured
Ceres in Pisces is read as nurture without a boundary: Allan is read as someone who feels what others need before they say it, and can give past the point of sense.
♡ ErosScorpio 2°47′ (moves 0.27° over the day)
near-Earth asteroid (433) · what draws them and how they desire
Eros in Scorpio sits in the sign the tradition links to it most closely: desire as depth and total exposure. Allan is read as uninterested in anything half-felt.
⚕ HygieaPisces 29°24′ (moves 0.33° over the day)
main-belt asteroid (10) · health, routine and what keeps them well
Hygiea in Pisces is read as health that rises and falls with what is absorbed from others. The reading has Allan needing solitude to reset.
⚸ Black Moon LilithTaurus 26°48′ (moves 0.11° over the day)
mean lunar apogee · the part that refuses to be tamed
Black Moon Lilith in Taurus is read as an unbargained appetite: for pleasure, for ownership, for a body that answers to nobody. Allan is read as immovable on those points.
Aspects to the asteroids and Lilith
Major aspects only, at a tight 3° orb. The Moon is left out because its position moves 13° across an untimed day.
- Eros conjunction Saturn 0.6°
- Chiron trine Jupiter 0.7°
- Chiron trine Neptune 0.7°
- Eros trine Sun 0.7°
- Ceres trine Pluto 2.2°
Method: JPL Horizons heliocentric vectors, 1700–2100, cubic Hermite interpolation; geocentric, true ecliptic of date, tropical; geometric (no light-time or aberration); Lilith = mean lunar apogee (Chapront/Meeus mean perigee + 180°).
Allan’s dominant planets
Scored from rulerships, dispositors and aspect count. Without a birth time there is no Ascendant or house to score, and the Moon's sign is left out where it could change with the hour.
1. ♃ Jupiter9.5 pts
traditionally rules the Sun sign, Pisces; in its own sign, Sagittarius; disposes Mars; 5 major aspects
2. ♆ Neptune9 pts
rules the Sun sign, Pisces; disposes Sun, Uranus; 4 major aspects
3. ♀ Venus4 pts
4 major aspects
A Jupiter-led chart is read as scale and optimism leading: Allan is read as reaching for the bigger version of any plan.
How the score is built
- Rules the Sun sign, Moon sign or Ascendant sign: 3 points each (traditional co-rulers of Scorpio, Aquarius and Pisces score half).
- Sits in a sign it rules: 2 points.
- Disposes another planet (that planet sits in a sign it rules): 1 point each.
- Angular: 2 points in the first or tenth house, 1 point in the fourth or seventh (timed births only).
- Every major aspect it makes: 1 point.
Dominance scoring is an AsterNym method. Other sites weight differently and can name a different leader for the same chart.
Configurations in Allan’s chart
Closed shapes among the ten planets under the site’s one aspect-orb policy. The Moon is excluded without a birth time, so a shape that needs it is not claimed.

Where this data comes from
Allan’s birth date and birthplace come from Wikidata Q223542, released under CC0, as do the occupations, works, teams and awards in the biography above. No documented birth time is available, so this chart is rated X on the Rodden scale, the astrological convention for how well evidenced a birth time is. Time-dependent results use a clearly labelled reference time and should not be read as their exact birth chart. Entries are matched to Wikidata by entity id rather than by name, kept only at day precision, and dropped where sources disagree on the date.
