1957 Daily UFO Histogram
Out of 529 *U* listings for 1957, 208 were in November and 323 in North America.The busiest days 05 and 06 November (67 total listings) coincided exactly with the Taurids meteor shower. This is the only major wave to do so.
Efforts to filter out meteors and other junk sightings will never succeed entirely.
The 3 busiest states were California (41), Texas (37) and New Mexico (33).
In spite of all the UFOs, not to mention meteors, there are no reports listed here for Idaho, Delaware, Vermont or Rhode Island. Nevada, Utah and Montana show only one sighting each.
Compare this to the 1947 Histogram.
