Reflections / Shadows / Symmetries = Antiscia

Planets in antiscia and contra-antiscia reflect each other across the cardinal axis. This axis is formed by the four seasonal turning points: the zero degree entry point of each cardinal sign. The cardinal axis is essentially the node of the Sun and is a point we all share. It is the intersection of two Great Circles: the ecliptic, which is the sun's path (i.e., the tropical zodiac), and the earth's equator. Planets connect in antiscia when they reflect or mirror one another across this axis. Like a planetary statement made by two planets in aspect or conjunction, planets in antiscia make a terrestrial (or mundane) statement: a statement for the world which is relevant for everyone. Therefore planets in antiscia can provide insight into the energy of the day, as well as help to enrich your natal and dynamic chart delineations. More on antiscia here...

Sun Mercury conjunction reflects Neptune by antiscia

To use the list of monthly antiscia below, simply blend the meanings of planets in combination.

All connections are within 30 minutes of arc or less.
Dates showing one planet indicate its ingress onto the cardinal axis (meaning it's at zero cardinal and ought to feature prominently that day).
Those with a (c) indicate contra-antiscia: symmetrical arrangement around the Aries/Libra axis, aka: equal rising signs.

In addition to the books I reference on this page, an online resource for planetary pairs and midpoints is this one by John Sandbach. Or you can simply apply your basic astrological understanding of the planets. Think of the pairs and combinations as conjunctions; and remember you can consider their shared or reflected dignity and reception.
