S73-38390 (6 Dec. 1973) --- An Earth-based photograph of the Comet Kohoutek in the sky on Dec. 6, 1973, when the celestial phenomenon was more than 70 million miles from the sun and some 119 million miles from Earth. This picture was taken from a dark mountain top area of Haleakala (Island of Maui) Hawaii, using a 35mm Nikon camera with a 55mm lens, a 300-second exposure at f/1.2 and with Tri-X film. The photographer was Frank Giovane. The indicated visible tail of the comet appears to be about 10 million miles long. Other reports have inferred that the length of the tail is up to 13 million miles. The Skylab 4 crewmen have reported that Kohoutek's tail-length was from two to three degrees or from four to six million miles as viewed with the naked eye from the Skylab space station in Earth orbit.
