Scientific paper

Observational evidence is presented for dust particles heavier than 0.01 millionth of a gram expelled from Comet Halley. Dust emitted around 1.5 AU pre-perihelion, the point in orbit where a probe would fly through the comet in 1985, should have contributed to an anomalous tail that could have been observed in 1910. From positions of the trailing boundary of the ordinary dust tail at that time, it is concluded that the production of dust started to increase steeply at 0.7 to 0.8 AU before perihelion. Observations in late January 1836 are used to derive the production of dust vs. time and the the expected number of large-particle impacts on the protective shield of the 1985 flythrough probe. From data on other comets, it is estimated that the size distribution for large particles is likely to vary inversely according to the fourth or slightly higher power of the size.
