Calculating moon horizons of a QTH

Hi all,
At the moment I'm just curious, but how do I go about calculating the limits for where the moon will ever be from my QTH? I know that I don't need full 360x90 degree coverage, and I can predict where the moon is at any one instant using various programs, but how do I know for instance that the moon will say only ever be from 090 -N - 270 degrees? Is there a program or do I sit down and work it all out from the algebra?

73,
Joe

Have a look at this page: http://www.jgiesen.de/sunmoonpolar/
I think the graph in the grey box (MoonAzimuth) is what you want ... perhaps.
(You'll need Java installed, and use IE - it doesn't work for me with Firefox)

Regards,
Dave.

Works fine with my Firefox - but suggest that the sun is south of me in June. I think that it has a bug for the southern hemisphere. Thanks for the pointer though.
