    Lowell Observatory astronomer Seymour Hess reports a disc

    Astronomer Seymour Hess said that while walking the Lowell Observatory grounds at lunch he followed a small round gray object with a 4-power telescope as it passed in front of a cloud, traveling at right angles to the wind. Asked by reporters, Williams Air Force Base said it knew of nothing like it.
