The Ohio State University Radio Observatory was a Kraus-type radio telescope located on the grounds of the Perkins Observatory at Ohio Wesleyan University in Delaware, Ohio from 1963 to 1998. Known as Big Ear, the observatory was part of Ohio State University's Search for Extraterrestrial Intelligence (SETI) project. The telescope was designed by John D. Kraus. Construction of the Big Ear began in 1956 and was completed in 1961, and it was finally turned on for the first time in 1963. The main reflector of Big Ear—The Flat Reflector—measured approximately 103 meters by 33 meters, giving it the sensitivity equivalent to a circular dish measuring nearly 53 meters in diameter. The observatory…

Asteroids In the Fields of View of the “Big Ear” Radio Telescope at the Time of the Wow! Signal. Using the JPL/NASA “Small Body Identification Tool” and the Minor Planet Center “MPChecker,” I found the asteroids that were in or near the fields of view of the Ohio State University Radio Observatory (the “Big Ear”) at the time of the “Wow! Signal,” because no one else had checked asteroids in decades. As of November 6, 2025, I had found 12 asteroids in the original fields of view as defined by Ehman, two asteroids in the new fields of view from Méndez, and 23 “near misses,” asteroids just outside those fields of view. I note that one asteroid found, 28431 (1999 XO136), has an oddly high geome…
