“…This diffuse comet was discovered by the IRAS spacecraft but was not reported to the Central Bureau for Astronomical Telegrams until a week later, when it was independently discovered by two ground‐based observers, only 8 days before closest approach! The nucleus of comet IRAS‐Araki‐Alcock was estimated to have a radius of ∼4 km [20] so it would have likely resulted in a major global catastrophe if it had struck the Earth.…”

“…This feature is apparently transient, since it was not present in spectra of comet Halley taken at the end of 1985 . Such a feature was not present in the spectrum of comet West 1976 VI (Oishi et al 1978) nor in comet IRAS-ArakiAlcock 1983 VI (Hanner et al 1985), but was recently detected in comet Wilson 19861 (Brooke et al 1987, Allen andWickramasinghe 1987).…”

“…Surface temperatures are also seen to exceed T eqBB in ground‐based observations of comets in which it is thought the majority of the infrared flux was due to the cometary nucleus rather than coma dust [ Hanner et al , 1985; Tokunaga and Hanner , 1985; Veeder et al , 1987]. Again, these higher temperatures are consistent with slow rotation of objects with dark surfaces.…”
