How do you Produce Ephemerides?

C2A lets you produce ephemerides for the Sun, Moon and planets, as well as asteroids and comets from the knowledge of their orbital elements. In this section we shall see how to quickly generate ephemerides for the Sun, Moon and planets for the current month.

The ephemerides generator tool is displayed by using the Ephemeris generator command in the Tools menu. Once the window is displayed, the first thing to do is to check all the objects for which you wish to generate ephemerides. In our case, just click the All button in the top left of the window.

Now insert the dates delimiting the current month. The simplest way to do this is to use the automatic month selection button in the top right of the window (this is the button is identified by 2 exclamation marks). See that this resulted in the start and end dates being defined as the first and last days of the month and that the step interval is 1 day. Then just click the “produce ephemeris” button to update the results table with the requested ephemeris. The figure below shows the date area and the position of the “produce ephemeris” button.

The Tool for producing ephemerides page describes the components of this interface.
