Sighting waveHudson Valley Wave (1982–1986)
Over 5,000 sightings of a large, silent, boomerang or triangular object were logged across the Hudson Valley of New York and western Connecticut over four years; J. Allen Hynek led the field investigation in his final years.
What's documented
Beginning the night of 31 December 1982 over Kent, New York, the Hudson Valley wave produced more than 5,000 reports across Putnam, Westchester, Dutchess, and Orange counties in New York and Fairfield County in Connecticut. The reported object was consistently described as a large, silent V or boomerang shape with multiple lights moving at very low altitude. J. Allen Hynek, founder of the Center for UFO Studies (CUFOS) and former Project Blue Book scientific consultant, personally interviewed hundreds of witnesses during the wave’s final years. He co-authored Night Siege with Philip Imbrogno in 1987, his final book before his death.
