If you can run a Windows program, my Lunar software will give you the geocentric and topocentric separation angle rates per minute of time. The values are calculated from the space velocities of the bodies (it's not necessary that one body be the Moon) with no allowance for aberration and refraction, so the values are not rigorously correct. But I think the error is not significant. http://home.earthlink.net/~s543t-24dst/lunar3/index.html
