See Kennedy'sE. S. comments on the literature of comets: “Comets in Islamic astronomy and astrology”, Journal of Near Eastern studies, xvi (1957), 44–51. There is very little else on comets per se, other than the general comments in Encyclopedia of Islam2, ed. by BosworthC. E.et alii (Leyden, 1960–), s.v. “Nudjum” (P. Kunitzsch). On historical comets overall, see MarsdenBrian, Catalog of cometary orbits (Cambridge, Mass., 1975); KronkGary, Comets: A descriptive catalog (Hillside, N.J., 1984); MoorePatrickMasonJohn, The return of Halley's Comet (New York, 1984); SchoveD. J., Chronology of eclipses and comets AD 1–1000 (Woodbridge, 1984) [this study needs to be used cautiously, as there are no references given to the Arabic material]; YeomansDonald, Comets: A chronological history of observation, science, myth and folklore (New York, 1991); EdbergStephenLevyDavid, Observing comets, asteroids, meteors and the zodiacal light (Cambridge, 1994); SchaafFred, The comet of the century (New York, 1997); and Kronk'sGary forthcoming book, Cometography (thanks to him for allowing me to have access to the relevant material).

E.g., in IyasIbn, Bada'i’ al-zuhur fi waqa'i’ al-duhur (Cairo, 1984), ii, 333. In al-Mufaddal b. Abi al-Fada'il, History of the Mamluk sultans in Patrologia orientalis, xii, 434–5, a star is said to have appeared when the 'Abbasid caliph was proclaimed in Egypt in 1259, which is unknown from other sources. Comments about the relative use of hagiographical material and other questionable sources appear in Number 1 and the Appendix.
5.
The name shows that the Arabs did not know where to place them, since najm is usually a star, while kawkab is usually a planet. Therefore, they are either “stars with tails” or “planets with tails”, with no real consistency.

Since this appearance of Halley's Comet apparently affected the course of the revolt of the Muslims of the Hijaz, and terrified the Syrian soldiers sent to subdue them, it is very possible that an aside of Khalifa b. Khayyat, Ta'rikh (Najaf, 1967), i, 229, where he says “God sent the heavens against them …” could refer to this (it is uncertain what exactly he means by this, though), and may have been mentioned in the Rish Melle: BrockS.

Dating this appearance is based on the assumption that the previous part of the text actually refers to 143/760. If so, then this is the comet mentioned by Theophanes, Chronicles (ref. 6), 122 for 145/762: “In this year an apparition appeared in the east, and Fatima's son was killed”, meaning the rebel Muhammad al-Nafs al-Zakiyya, who revolted in Nov.–Dec. 762. The dates given in the text would correspond to 28 July 28–mid-October 762 and in this way the appearance of the comet was apparently the deciding factor in his decision to revolt.

There must be some error here, since the author gives a Christian date which translates to 13 Feb. 1060. It is difficult to tell which one is correct, unless once again there is a mix-up in the names of the Christian months.
These names are difficult to identify. One would assume that Coptic is the language from which they are derived (since the writer is a Coptic ecclesiatic); however, it would appear that the Arabic or Syriac meanings of safud/safudo, “spit, dart, a poker”, and fanus, “a torch, lantern, lamp” (from the Greek phanos), are sufficient.

In Cometography (ref. 3), Kronk notes Chinese accounts that compare the comet to the planet Venus, which would imply a magnitude of about −4.5, at the margin of daylight visibility. Marcus (personal communication and Marcus and Seargent, op. cit. (ref. 94)) comments that due to forward scatter geometry in the interval 1066 April 18–24, the comet's brightness, with its 1986 appearance considered as a baseline, could have been markedly enhanced in 1066, to magnitude −7 on the evening of April 22, −4.5 on April 23 and −2.5 on April 24.

Easter during this year fell on 1 April, which constitutes something of a problem. However, there are some difficulties with the tables consulted, and the next year's Easter of 20 April would be a perfect match. This remains a question-mark.
