There is a full moon on Monday and I don't have any trouble reading the times for moonrise but what I never know for sure is how to tell WHERE on the eastern horizon the moon will appear. Does anyone know how to tell?

What you want is the azimuth at the rise time:

Sun/Moon Position Calculator (http://www.largeformatphotography.info/sunmooncalc/)

Is the Azimuth equivalent to 90 = East, 180 = South, etc?

Not to be a smart a$$, but couldn't one just look for the bright light?

Yup.

By the time you see the bright light, it's nearly too late to get in position for shooting the moon.

Well, yes, Monday's moon will rise right near sunset so you can get some foreground exposure and properly expose the moon. Or, at least hopefully. But yes, if you are putting something in the foreground, it's good to get lined up before the moon rises because once it comes up the optimum time is right then. It moves too fast and then the contrast gets to be too much.

A couple of years ago I tried to do what the OP wants to do. The city hall in my town has a very nice dome atop the roof and I've often thought of capturing it with a full moon (or nearly full). But, there is only really one good vantage point where you can get a good composition of the dome and the moon will be in the background. BUT, it will only look good in the twilight, so that's basically two or three days per month and with the seasons the moon changes it's apparent position, limiting the opportunity to only a few days per year.

Twice I tried when the moon was in the right spot, but it was cloudy!

Then I kind of lost interest. I figured it would be easier with Photoshop ;)

A little late for the full moon, but I'm sure another one will come along.

The best way to find out positioning of the moon, or any astronomical object for that matter is Cartes du Ciel, a free planetarium software which you can download here: http://www.stargazing.net/astropc/

Another option would be to go to http://www.heavens-above.com/ and punch in your location and use the whole sky chart.

I use Stellarium (http://www.stellarium.org/).
CdC (Cartes du Ciel) is very powerfull, but a bite complex compared to Stellarium, especially when you want to surf on the sky. But i control my HEQ5-Pro Goto mount with Cartes du Ciel
