Midheaven Lines
MC lines connect locations where a selected natal body was culminating on the upper meridian at birth. Scope is explicit.
Overview
L belongs to the Sun/MC meridian condition; latitude-dependent display remains documented. This is the worked result for Midheaven Lines; it remains conditional and does not turn geometry or timing into a verdict. The comparison method is explicit: Choose one body, solve upper-meridian culmination from local sidereal time and the body’s right ascension, label its MC curve, and compare the same place’s relocation chart.

Definition and exact scope
MC lines connect locations where a selected natal body was culminating on the upper meridian at birth. The upper-meridian event depends on right ascension and local sidereal time; it is not a generic north–south longitude line.
Calculation or decision rule
Choose one body, solve upper-meridian culmination from local sidereal time and the body’s right ascension, label its MC curve, and compare the same place’s relocation chart. 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
at the birth instant, ☉ hour angle 0° and upper culmination at longitude L. L belongs to the Sun/MC meridian condition; latitude-dependent display remains documented.
Illustrative near miss; does not qualify: Using lower culmination and labeling it MC rather than IC.
School, model, and context variants
A MC curve cannot guarantee career prominence, authority, reputation, or public success; its body label, natal condition, map precision, and practical place evidence remain required.
Product, safety, and verification boundary
