Circular Path Wheel
Sun stays in the center. Mercury starts at the innermost active ring. Outer bodies and asteroids move outward in corrected order, with retrograde loops made visible by radial drift.
Flat Retrograde Motion Chart
Horizontal axis is time. Vertical axis is zodiac longitude from 0° Aries to 360°. Retrograde appears as a downward reversal on the line.
Date defaults
Start now defaults to January 1 of the current year, and end defaults to today.
Mobile layout
On phones, the chart now appears before the controls and uses a tighter layout so it fits the screen better on initial load.
Local resources
This build uses your local PHP endpoint, local Swiss Ephemeris files, local swetest executable, and local HamburgSymbols font file.
