Scientific paper

Observations used in this study include ≡75 published V magnitudes obtained with large telescopes (usually with CCDs) prior to July 1985 and 650 total magnitudes (out of >3000 published in the International Comet Quarterly) estimated visually with smaller telescopes during the period July 1985 - August 1986. The authors discuss the observed macroscopic light curve and provide preliminary least-square fits to the traditional power-law formula. Further work is needed to apply physically-meaningful formulae, based on models describing dust- and gas-production rates, to the observed light curve of P/Halley. They also briefly review brightness variations on smaller timescales (hours, days).
