I'm attempting to use an algorithm translated from Jean Meeus: Astronomical Algorithms. The algorithm in question finds a geocentric position of the moon given a certain day. I have been able to find the geocentric longitude of the moon, but I don't know what this longitude is in reference to. What would 0 degrees of longitude point to? Would it be the vernal equinox point like heliocentric systems or something else?
Thanks!
EDIT: I meant longitude, not latitude
