‘n the morning of June 2ist., 2t 0636, two meteorologists and an electronics
engineer were watching the radar scope to observe clouds moving in from the

mest. An echo appeared at O65 derrees, with the center of the refleetive

field on the 20 mile range ring. The brightness of the echo was the same as
that of the ground clutter, On the second sweep of the scanner(6 sec.) the
center of the raflective Semex field has moved about 1 to 5 miles. The

first echo still retained much cf its brigntness. The secong echo was cue
north sast of the first. Ey the time the scanner nade another sweep the

1. In accordance with established ATIC policies for the analysis co UFO reports,

1. Based on the information reported, it is the siete. of this office that
the signal reported was caused by ground clutter. A variation in the index of
refraction in the propagation medium, in this case the atmosphere, causes the R.F
beam to bend and strike the ground. The phenomenon reported in sweep three is

most likely caused by changes in the characteristics of the index of refraction.

2. In future reports involving radar detection of UFO's, it is requested that
the radar be identified, if possible, and the target size be estimated from the
spot size seen on the yadar indicator.
