Sun and Mars stand about sixty degrees apart today, a sextile, traditionally read as an easy, cooperative angle. The Moon is in Libra, a young crescent growing in the evening sky.

What is a waxing crescent moon?

A waxing crescent is the thin, growing sliver you see in the west just after sunset, in the first days after a new moon.

The Moon has pulled far enough away from the Sun for a lit edge to show, and illumination climbs from near zero toward half. Each evening it sits a little higher and a little brighter.

The traditional reading is early effort: a thing has started, it exists, and it is not yet convincing to anyone else. That is a description of a stage, not a prediction about how it turns out.

It pairs naturally with the small, unimpressive work that nobody claps for, which is usually where the outcome is decided anyway.
