I. Description of Incident

At 0105Z on 9 November 1952, a radar at El Vado, New Mexico, first observed a "blip" 20° wide, 45 miles and 145° from the station. The "blip" was clocked at front 600 to 1400 mph as it went off the scope at 130 miles. It soon returned on the same azimuth, came to within 65 miles of the station, hovered approximately two minutes, turned. and went off the scope again. It was observed a total of ten minutes.

During the sighting, the frequency of the radar set was changed 20 megacycles with no apparent change in the target.

II. Discussion of Incident

Many similar types of returns have been shown to be due to certain atmospheric conditions. It is very possible that this return was due to weather.

III. Conclusion

Weather caused the unusual radar return.
