How it works

Astralume by BasAmunRa takes your birth date, time, and place and maps the sky exactly as it appeared above you in that moment.

Astronomy first

Planetary positions come from VSOP87-based ephemerides, the same models used by professional astronomers. Time is converted to UT1 from your birth timezone, and house cusps are calculated using the classical Placidus method.

Interpretation, gently

Each placement — sun in sign, moon in house, ascendant — is presented with short, classical descriptions. We don't make predictions; we map the symbolism.
