How to read the rings
Violet hours, blue minutes and gold seconds form the inner clock. The brightest segment marks the current value.
Weekday, day and month follow. The narrow seasonal band changes at the calculated equinoxes and solstices.
The small event dots show lunar quarters across the year. Select a dot for its date and source.
The zodiac band and ten outer planetary tracks show longitude. Dashed planet outlines indicate retrograde motion.
Use zoom to inspect fine marks, or use the planetary register and event lists below.

Retrograde describes apparent motion as seen from Earth. Zodiac signs here are equal 30° divisions, not astronomical constellation boundaries.

Optional observations from NOAA. Geomagnetic activity is not a report of local aurora visibility.
