Hartung (this issue) has suggested that the Corvid meteor system, observed only once in 1937, may be the return of a clump of ejecta from the formation of a lunar crater, specifically an event recorded in the chronicles of Gervase of Canterbury on June 25, 1178, which Hartung (1976) has previously suggested may be an eyewitness account of the formation of the lunar crater Giordano Bruno. On the basis of this association, he predicts that another Corvid shower may be observed in 2003 or 2006. In this reply, I point out three difficulties with the hypothesis: (1) it is implausible that a clump of ejecta could be launched into heliocentric orbit with a low enough dispersion in velocity among separate pieces that it would produce a meteor shower in just one year and not others; (2) subsequent perturbations by the Earth on parts of the clump passing near the Earth but not impacting, would destroy the coherence of the clump on a time scale much shorter than the 759-year interval proposed; and (3) all else accepted, there are so many possible orbits that could yield a shower after 759 years that it is unlikely that a prediction of a return in a specific year would be correct. ¿ American Geophysical Union 1992
