Solar Arc Directions
Solar arc directs every natal point by the same arc traveled by the progressed Sun from its natal longitude. Scope is explicit.
Overview
Arc is +30° and directs the MC to 280° after normalization. This is the worked result for Solar Arc Directions; it remains conditional and does not turn geometry or timing into a verdict. The comparison method is explicit: Declare the progression key and arc definition, add the arc modulo 360° to each target, then calculate directed-to-natal aspects with narrow orbs.

Definition and exact scope
Solar arc directs every natal point by the same arc traveled by the progressed Sun from its natal longitude.
Calculation or decision rule
Declare the progression key and arc definition, add the arc modulo 360° to each target, then calculate directed-to-natal aspects with narrow orbs. The receipt retains the chosen input record, reference frame, tolerance, and version, then identifies the first step where an independent recalculation diverges.
Worked case and illustrative near miss
natal ☉ 100°; directed ☉ 130°; natal MC 250°; one-degree solar arc. arc is +30° and directs the MC to 280° after normalization.
Illustrative near miss; does not qualify: Moving each planet by its own secondary progression instead of applying one common solar arc.
School, model, and context variants
Solar arc positions are uniformly directed symbols, not the bodies’ actual sky positions and not guaranteed event timers.
