Visual observations of Comet Kohoutek from Skylab III

Sketches of Comet Kohoutek drawn by the author during operations on Skylab are presented. The sketches are black and white, with darker color implying a higher observed brightness. Sketches were also made of what the isophotes would have looked like if they could have been measured. In addition, color sketches made after the flight and corresponding to each of the inflight sketches are presented. The sketches show the comet at perihelion minus 10 days and at perihelion plus 1-9 days. Sketches show the comet changing appreciably in form, color, texture, and length after perihelion. The sunward spike, visible at perihelion plus one day, is no longer visible at perihelion plus 4 days.
