Charts

In the next four charts are graphs of the sun's or moon's elevation angle as it was tracked by using the Low Flying Aircraft Monitoring System. These angles are plotted on a graph and compared with the U.S. Naval Observatory's predicted elevation angle for the sun or the moon.

The sun's elevation angle, U.S. Naval Observatory data vs. the Low Flying Aircraft Monitoring System's camcorder measurements of the sun's elevation angle, 2/2/01 Camarillo, CA, 7:20-11:10 AM

The sun's elevation angle, U.S. Naval Observatory data vs. the Low Flying Aircraft Monitoring System's camcorder measurements of the sun's elevation angle, 1/20/01 Camarillo, CA, 12:10-4:00 PM

The sun's elevation angle, U.S. Naval Observatory data vs. the Low Flying Aircraft Monitoring System's camcorder measurements of the sun's elevation angle, 12/27/00 Point Mugu, CA, 2:00-4:00 PM

The moon's elevation angle, U.S. Naval Observatory data vs. Low Flying Aircraft Monitoring System's camcorder measurements of the moon's elevation angle, 1/03/01 Point Mugu, CA, 3:13-3:34 PM. (There are photographs of 3 moon observations on the web site's picture page.)

This chart shows a graph of the Low Flying Aircraft Monitoring system camcorder's angle measurements of a "giant home made protractor."

The protractor elevation angle, The radius of this protractor is 57.3 inches. This means that for every 1 inch of distance traveled on the circumference of the protractor is equal to 1 degree of angle traveled when viewed from the center of the protractor. There are photographs of the protractor are on the web site's "picture page."

This chart shows a graph of the Low Flying Aircraft Monitoring system camcorder's angle measurements of a vertical ruler.

The vertical ruler elevation angle, the camcorder is placed 94.5" away from the ruler. This means that angle measurement to the ruler is equal to the ATAN (measurement in inches on the vertical ruler/94.5 inches). There are photographs of the vertical ruler are on the web site's "picture page."
