Sun and Mars stand about a hundred and twenty degrees apart today, a trine, traditionally read as the easiest of the major angles. Sun and Saturn stand about ninety degrees apart today, a square, which astrologers read as friction between two ways of moving. The Moon is in Libra, near its last quarter, shrinking toward new.

What does the Sun or Moon in Libra mean?

Libra is a cardinal air sign ruled by Venus, and it reads as the search for a fair arrangement between people who both have a point.

The Sun enters Libra at the September equinox and stays about a month. A Libra Moon lasts about two and a half days and usually reads as a stronger than usual pull toward company, pleasant surroundings and keeping the peace.

Cardinal means it takes initiative, which in Libra looks like proposing the compromise rather than winning the argument. Air means it thinks it through in words. Its cost is that fairness to everyone can turn into silence about what you want, and saying the unpopular half is a choice available to you.

In the tropical zodiac Libra begins exactly at the September equinox, one of the four seasonal anchors the whole system is built on.
