Moon elevation and azimuth measured at Bivens Arm

Sven Grahn

The azimuth and elevation numbers have been computed using the following website: www.jgiesen.de/elevazmoon/index.htm

The position of the dish at Bivens Arm was 29.630246 N 82.349656 W. Considering that the timing accuracy may be about a minute and that there is refraction (parallax) at S-band. Also, the dish was moved every four minutes. Taking all these factors into account it it obvious that we were able to point the antenna rather accurately at the Moon.
