I am finding the Azimuth and Altitude and relative size of the Moon at a particular time each day and looking for patterns in the data I find. To find the Altitude and Azimuth I use the device shown below to find the moon and measure the angles.

To find the percentage, I print a picture of the day’s Moon, cut out the full Moon and weigh it. Then, I cut the fraction of the Moon that is lit up (eg: Half Moon, Crescent Moon) and weigh it. To get the percentage, I divide the weight of the fraction of the Moon by the weight of the full Moon and multiply that by 100.

View Observations
  • The Moon isn’t up every night, sometimes it is only up in the day.

View Theories
  • Here is some non-official observations I made based on the data:
    1. The Moon’s Altitude limit is 180 degrees.
    2. In the day, The Moon moves up and to the West until it reaches 123 degrees Altitude. Then, it starts moving down and to the east.
