Annual Review of Earth and Planetary Sciences, 1982
Since 240 B.C., Chinese observers have documented a nearly unbroken record of scientifically useful observations of Periodic Comet Halley (P/Halley). Investigations of the comet's motion by Western astronomers are discussed, taking into account the first successful prediction of a cometary return by Halley (1705), computations conducted by Rosenberger (

Advances in Space Research, 1998
In combination with the authors' previous observation about the splitting of Comet Halley in March 1986, the events involving the sharp, straight feature in the antisolar direction observed in the head of Comet Halley in 1910 (such as those occurring on May 14, 25 and 31, and June 2) are rediscussed.

Observing Halley's Comet [PDF]
European Journal of Physics, 1985 The comet should be observable with small telescopes or binoculars for about a year from the late summer of 1985, and with the naked eye for a substantial part of that period. The author describes in detail where to look, and makes suggestions about what to look for. Observers in the Southern Hemisphere will be favoured on this occasion.

At its 1986 apparition, Halley’s Comet became by far the most studied comet in history with five space probes encountering it and a multitude of ground based telescopes observations carried out by both amature and professional astronomers. In this overview we will discuss only the part of the data set that is of most interest ot infrared astromers ...
