    Description
    Robert Hooke's observation of a comet and its tail on 4 September 1682. This comet later came to be known as Halley's Comet.

    Cl.P/24/88 contains observations of comets by Robert Hooke between 1680 and 1683. These must be the papers found inserted into Hooke’s copy of the star chart Uranometria (Augsburg: Christoph Mang, 1603) by Johannes Bayer (1572-1625), which was purchased by the naturalist John Woodward FRS (1665-1728) at an auction of Hooke’s library after his death. Hooke’s copy of Uranometria is likely now the copy in the British Library (Maps C.10.a.17). Hooke used Bayer's symbols for stars in his observations.

    Hooke read a paper about the nature of comets based on some of these observations at the meeting of Royal Society on 25 October 1682, though it is unlikely that Hooke read out the entire discourse, which runs to 40 pages as printed in his Posthumous Works (1705), pp. 150-90: ‘A discourse of the nature of comets’.
    Object history
    At the meeting of the Royal Society on 25 October 1682, ‘Mr. Hooke read a discourse concerning comets, and in this first part of it gave an account of several of his own observations concerning the appearances of the comets in 1680 and 1681; in which he mentioned several new and wonderful appearances of them, taking notice of the other remarks concerning them, as of their place, position, magnitude, motion, way or course, only in short, and by the bye, referring his observations in those particulars to the other parts of the discourse’ (Birch 4:162).

    Hooke's observation of a comet on 4 September 1682 is described in R. Hooke, Posthumous Works, ed. by Richard Waller (London: S. Smith and B. Walford, 1705), pp. 150-90: ‘A discourse of the nature of comets': 'The Nucleus was pretty clear and round, but the Blaze from it was only two Emanations of a kind of Parabolick Figure on each side, as in the figure' (p. 161).
