What the chart says
Simon, according to the stars
Core essence
Simon is warm the way the sun is warm: not trying, just doing it. The core of Simon is a big open heart and a need to be seen loving with it. They are generous with praise, with time, with the spotlight when they trust you, and they will remember every kindness you paid them for years. Loyal to a fault, and glad of the fault.
The vibe
Underneath, Simon processes by talking. The Moon in Gemini means a feeling is not real until it has been said out loud, ideally to two people, ideally with a joke attached. What Simon needs to feel safe is someone who will listen to the whole thought, including the three tangents, without rushing them to a point.
How Simon creates
How Simon makes things happen: they grow upward. A Yang Wood day master is the tree, the one with a direction and the patience to keep at it through a bad season. Simon builds in the open, wants to be useful, and is at their most creative when there is something to reach for. Bend rather than break is the lesson they learn a few times.
Instinct
Instinct: Simon is sharp and confident, a Rooster year, and their gut reaction is to say the true thing out loud. Observant, hardworking, honest, and proud of looking the part. The Fire year turns the volume up: warmer, bolder, more expressive, harder to overlook.
Purpose
Purpose: Life Path 5 is the free spirit. Simon 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: sloppiness, and being told they are overthinking it. Mars in Virgo means Simon channels energy into fixing, sorting, getting it right, and gets sharp when others do not care. The critic turns inward first. Give them a problem worth solving and watch them come alive.

Overhead at Cambridge at 9 p.m. that evening: Eltanin of Draco, within 0.7° of the exact zenith.

At 52.2°N there are stars that never set at all. Vega, Capella and Deneb stay up year round.
The trade is at the other end of the sky: nothing south of −37.8° declination ever rises from here, which puts Canopus, Rigil Kentaurus, Achernar, Hadar, Acrux, Mimosa and Toliman permanently out of view.

Where this comes from, and how it is worked out
Simon’s birth date and birthplace come from Wikidata Q334039 (CC0), as do the occupations, works and awards above. With no documented birth time this chart is rated X on the Rodden scale, the astrological convention for how well evidenced a birth time is. The banner above lists what that leaves out. Entries are matched to Wikidata by entity id rather than by name, kept at day precision, and dropped where sources disagree on the date.
Tropical zodiac, whole-sign houses, modern rulers. Aspects on the western_v1 orb policy; minor ones at 1.5° to 2.5°, skipped where a major already holds. Minor bodies from JPL Horizons heliocentric vectors, Lilith as mean apogee. Dominance is an AsterNym score — rulerships, dispositors, aspect count — so other methods can name a different leader.
