Blueprint Ephemeris is a complete planetary ephemeris indicator that computes real-time astronomical positions for all 10 solar system bodies directly inside TrendSpider \u2014 no external data feeds or APIs required.<\/p>\n

## OVERVIEW<\/p>\n

Computes geocentric and heliocentric coordinates for the Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, plus North and South lunar nodes (mean or true).<\/p>\n

Bodies: \u2609 Sun \u00b7 \u263d Moon \u00b7 \u263f Mercury \u00b7 \u2640 Venus \u00b7 \u2642 Mars \u00b7 \u2643 Jupiter \u00b7 \u2644 Saturn \u00b7 \u26e2 Uranus \u00b7 \u2646 Neptune \u00b7 \u2647 Pluto \u00b7 \u260a North Node \u00b7 \u260b South Node<\/p>\n

## Theories:<\/p>\n

VSOP87D \u2014 Mercury through Neptune (Bretagnon & Francou, 1988)<\/p>\n

ELP2000-82 \u2014 Moon (Chapront-Touz\u00e9 & Chapront, 1983; Meeus truncation)<\/p>\n

Meeus Series \u2014 Pluto (Meeus, "Astronomical Algorithms", 1998)<\/p>\n

Accuracy (validated against JPL DE440 via Skyfield, 2000\u20132050):<\/p>\n

Sun 0.004\u00b0 \u00b7 Mercury\u2013Neptune 0.005\u00b0\u20130.017\u00b0 \u00b7 Moon 0.062\u00b0 \u00b7 Pluto 0.059\u00b0<\/p>\n

All bodies under 0.1\u00b0 RMS.<\/p>\n

## DISPLAY MODES (19)<\/p>\n

Per-Planet: Longitude, Speed, Declination, Latitude, Right Ascension, Helio Declination, Helio Radius, Geo Distance, Angular Size, Elongation, Signed Elongation, Phase Angle, Illuminated Fraction<\/p>\n

Pair: Aspect Angle, Midpoint, Synodic Phase, Speed Diff<\/p>\n

Aggregate: Avg 6 Planets, Avg 8 Planets<\/p>\n

## FEATURES<\/p>\n

\u2022 Geocentric\/heliocentric toggle (Sun and Moon always geocentric)<\/p>\n

\u2022 Individual on\/off toggle per planet \u2014 all enabled by default except Moon and nodes<\/p>\n

\u2022 Two-body pair modes with dedicated planet dropdowns<\/p>\n

\u2022 Aggregate average longitude (6 or 8 planets)<\/p>\n

\u2022 Reference lines at 30\u00b0 intervals (zodiac boundaries or aspect degrees)<\/p>\n

\u2022 Future projections up to 100 bars ahead<\/p>\n

\u2022 Mean or true lunar node selection<\/p>\n

## HOW TO USE<\/p>\n

Load the indicator to see all planets in longitude mode. Toggle bodies on\/off, switch display modes, or select a Pair\/Avg mode. Enable Reference Lines for zodiac or aspect markers. Set Projection Bars to extend lines into the future.<\/p>\n

## THEORY & REFERENCES<\/p>\n

All positions computed from first principles \u2014 no external ephemeris services. Truncated analytical series implemented directly in JavaScript.<\/p>\n
