Daily UFO Histogram:
Western Hemisphere
This histogram shows daily UFO sightings frequencies for the
Wastern Hemisphere, for all years combined.
The dividing line is shifted ten degrees West of Greenwich
to exclude western-most Europe and Africa.
North America (9088 records) and the USA (8243) predominate, with another 707 in Canada, and 1229 in South America.
The peak in early July is not for a single flap, but rather the combined effects of separate waves in 1947 and 1952. A third wave of UFOs 1950 centered around March of that year.
The USA counts for 44.4% of all *U* data. The other 55.6% refutes the stale canard that "UFOs are mostly seen in the USA".
