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. ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________
