1. Data is too limited to make an analysis. It appears, however, that
anamalous propagation is a strong possibility since the observer indicated that
face that the target ("three times the size of a freighter") was not visible at
20 miles with excellent visibility conditions seems to preclude the target as.

altitude changes. The radar could have broken lock on a balloon at relatively low
altitude and then locked on another at higher which vould have given the
imression that a rapid ascent target had occurred. Efforts to sight the
target visually failed which would indicate either a small target such as a
balloon or possibly a false target.
very small possibility since a second same target.
2. The second of these reported sizhtings seems to indicate a false target
because of the erratic nature of the signal return and efforts to sight the target
visually failed during daylight hours. False radar targets occur occasionally,
due mainly to atmospheric and weather phenomens, but sometimes due to spurious
signals sources of interference.
