Analemma with current Sun Position

This applet displays an analemma divided into the twelve Zodiac signs (tropical system), and also shows the current position of the Sun relative to the signs. You need to have Java (not the same thing as Javascript) enabled in order to see it.


The analemma is shown as if you were looking up into the sky at the Sun. Analemma images based on shadows cast on the ground or on a wall by some fixed object (such as the gnomon on a sundial) will be mirror images of this.

Each colored region represents one astrological sign (Tropical system). The four cardinal signs (the ones the Sun enters at Solstices and Equinoxes) are labeled in larger type than the others.

Move the slider to change the date used for the calculation. The slider is calibrated in days: Zero = today, Positive values = dates in the future, Negative values = dates in the past.

Sign transition dates may differ slightly from other published sources due to rounding, time zone differences, and the like.
