A documented birthplace cannot supply a horizon
The Frank Lloyd Wright Foundation names a calendar date and Richland Center birthplace. Those facts locate a record in history, but the local horizon at a particular moment is still unknown. A building, an artistic style, or a later reputation cannot be used to back-calculate the missing birth hour.
Planetary sign range for the recorded date
The possible signs cover hourly positions across the recorded date and every civil-day UTC offset from +14 to −12. Without a verified birth hour or offset, a body that crosses a sign boundary remains unresolved.
| Body | Possible signs | Reading note |
|---|---|---|
| Sun | Gemini | Same sign in all hourly samples |
| Moon | Leo / Virgo | Birth hour or offset may change the sign |
| Mercury | Gemini | Same sign in all hourly samples |
| Venus | Taurus | Same sign in all hourly samples |
| Mars | Leo | Same sign in all hourly samples |
| Jupiter | Pisces | Same sign in all hourly samples |
| Saturn | Scorpio | Same sign in all hourly samples |
Geocentric tropical positions. A sign shown twice cannot be narrowed down without a documented birth time and historical UTC offset.
