The ephemeris

Where the planets stand.

An ephemeris is the daily table of planet positions that every chart is drawn from. Ours is worked out live, in your browser, when you open the page: nothing is copied from a printed table, so you can check any line against any other source you trust.

Retrograde means a planet looks, from Earth, to be moving backwards against the stars. No planet really reverses; it is an effect of viewpoint, the way a slower train seems to roll backwards when you pass it. The Sun and Moon never appear retrograde. The flag is worked out by comparing the planet's position with its position a day later.

The next seven days

The Sun changes sign about once a month; the Moon changes sign about every two and a half days, which is why the Moon column moves and the Sun column mostly does not. Each row is that day at midday, Universal Time.
