How does one compute the right ascension and declination of the Moon at a given time (or for that matter, the altitude and azimuth)?

  • $\begingroup$ Do you want to know the equations or just a calculator? $\endgroup$

  • $\begingroup$ I assume you don't want to use an online/email solution like ssd.jpl.nasa.gov/?horizons is that correct? How much accuracy do you seek? You can replicate HORIZONS calculations if you really want to. I assume you're looking at the geocentric ra/dec/alt/az? The actual position of the moon varies up to 1 degree depending where on Earth you are. $\endgroup$

  • $\begingroup$ The computation of the position of the Moon is rather complex (depending on the desired accuracy) and requires a few pages of equations. These can be found in e.g. this paper: esoads.eso.org/abs/1988A%26A...190..342C $\endgroup$
