1. These four messages report radar sightings from three (3) stations in the
same general area over a period of a little over four ()hours. It is probable that
the same object or phenomenon caused four different radar sightings. The object
appeared to orbit in a relatively small area. In addition, a possible weather balloon
was reported station.
2. Although fighters were unable to verify an object, the possibility exists
that a weather balloon could have caused the radar paints. Some other cause such as
weather or anomolous propagation phenomena is also possibility.
