Solar-proximity classification with source-dependent boundaries
This label can be calculated only after the source's solar-proximity range and priority between nearby categories are stated. It is a chart rule based on a coordinate separation. It should not be read as an observational visibility report: visibility also depends on sky brightness, altitude, atmosphere, magnitude, and observer conditions.
