## CONFIDENTIAL A sky phenomena which had the appearance of a flaming red cone trailing a gaseous green mist appeared in the southwest skies of Wilmington, Ohio, between 7:20 and 7:55 P.M. Jan 7, 48. The sky phenomena hung suspended in the air at intervals and then gained and lost altitude at what appeared to be terrific bursts of speed. The intense brightness of the phenomena pierced thru a heavy layer of clouds passing intermittently over the area and obscured other celestial phenomena. NOTE: See account of an unamed comet due in the northern hemisphere approx Jan 1. attached. See incidents 48a, 48b, 48c, 48d & 33, 33a, 33b, 33c, 33d, 33e 33f and 30 and 32.
