Photometric data collected during the preperihelion phase of the passage of Comet Halley are discussed in terms of the observed brightness variations and the rotation period of the comet. The primary data were collected at four different terrestrial observatories. Reflected light from the nucleus within 8 AU distance is determined to be only partially responsible for the photometric variations, leading to the conclusion that it is at the present time not possible to quantify the rotational period of a comet by its photometric variations. The behavior of the brightness variations at various distances from the sun indicated that outbursts are not temperature dependent and that the energy released is proportional to the energy stored at a given distance from the sun.
