Sun/Moon/Mercury midpoint combinations

Sun/Moon is the midpoint of heart and soul, right in the middle of the Sun and the Moon in your chart*). The midpoint defines what is motivating you. Writers are often motivated by Mercury, the symbol of communications, the messenger. And Mercury is often connected with Sun and Moon in their charts.

Here are a few examples of midpoint combinations:

J.K. Rowling (she wrote Harry Potter): Mercury conjunct her Sun/Moon
Lewis Carroll (Alice in Wonderland): Sun semi square Moon/Mercury
Martin Luther King: Moon semi square Sun/Mercury
Belgian author Hugo Claus: Moon semi square Sun/Mercury
Maigret: Sun square Moon/Mercury
Agatha Christie: Moon conjunct Sun/Mercury
Jean Auel: Mercury conjunct Sun/Moon

When Mercury is in hard aspect with your Sun/Moon midpoint you will be especially motivated by discussions, writing, speaking and communicating in general. When there is another combination of Sun/Moon/Mercury in your chart, you will communicate with heart and soul.

*) For more about calculating and interpreting midpoints, use this link to Astromarkt, the site with background info for this blog. In short:
The Sun/Moon midpoint is the equavalent of (Sun + Moon)/2. Of course, to calculate this you need to use the degrees of the 360 degree circle. A Sun in the 10th degree of Taurus is at 40 degrees, a Moon in the 20th degree of Libra is in the 200th degree. The midpoint Sun/Moon of this example combination is at 120 degree (zero Leo). If Mercury is in the 1st degree of Taurus there is Sun/Moon square Mercury. (Don't use more than 2 degrees orb). Now that I write this Sun/Moon is almost square Northern Node (at midnight GT). That means that motivation comes from a group of people (family, nation, tribe or community), like 'the people' or 'clients' or 'fans'.
