When it crosses the eastern side of the horizon plane it is rising / setting (circle).

Describe the location of the moon in the sky of the horizon diagram at bottom. Use direction words (like north, west, etc.) and estimate its altitude in degrees.

If we know the moon's position in the sky and its phase, we can estimate the ____________. In general, knowing any two of the following three things allows us to estimate the third:
1. moon's position in the sky

Question 1: We can determine the appearance of the moon based on the orientation of the moon and sun with a simple heuristic. In the figure below, bisect the moon twice.
a) Draw a line (perpendicular to the direction of sunlight) that shows the half of the entire moon that is illuminated and shade the shadowed …show more content…
First we move the moon to the full position by dragging it, or selecting ‘Full Moon’ in the phase name drop down list. Next, click on and rotate the earth while keeping an eye on the horizon diagram in the lower right corner. Rotate the earth until the moon just disappears below the western horizon. You should verify that this occurs at 6:00 AM. Complete the rest of the rising and setting times in the table above.
Question 4: Describe the relationship between the values of the meridian times and the rising and setting times in your table. ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________
