Planetary positions are computed using the astronomy-engine library, which implements the VSOP87 planetary theory for high-precision solar system calculations. Star positions are computed from J2000 right ascension and declination coordinates using local sidereal time for the event location. Times are approximated to local evening hours where exact times are unavailable in the source record. The purpose of this tool is correlation analysis — identifying whether bright planets (particularly Venus and Jupiter) were in positions that could account for misidentification, and documenting the astronomical context for cases where misidentification is ruled out by additional evidence such as radar confirmation or military pursuit.
