I've made a couple of screen shots but you aree going to have to specify what do you need for that story.

Thank you so much, that really helps a lot! Wow. For the story all I really need to know is how long the earth is in view when it's above the lunar horizon on Mare Orientale? Note that I have not seen any actual renderings of what the earth would look like from orientale (or any other part of the libration zone,) you may be the first person to do this?
I am shooting for as scientifically realistic a scene as I can get. Imagine being on a base somewhere on the outer part of Mare Orientale. What would the earth look like *over time*, as in, month to month (such as a month is on the moon?) As best as I can work out, the earth peeks over the horizon for about 3-4 earth days per 28 day lunar cycle due to libration, then falls for the remainder under the lunar horizon. But this is just a rough guess, I am trying to verify what the actual time would be for earth to be visible from an observer on the moon.
