CorrespondenceCorrespondanceDear Sir,ECLIPSE CONJUNCTIONSIn connection with my article “Conjunctions of Jupiter withthe Moon or Sun in Eclipse” (JRASC, 91, 74, 1997), I recentlyreceived a copy of Jean Meeus’ new book Mathematical AstronomyMorsels (Willmann-Bell 1997). In it Meeus refers to a similararticle, including an explanation, co-authored by him, J. vanMannen and G. P. Können in the Journal of the British AstronomicalAssociation (Volume 87, no. 2, pp. 135–145, February 1977).Not having access to the JBAA, I have not seen the paper, butI assume that the explanation given there is similar to my own.Consequently, I cannot make any claim to priority in explainingthe Jupiter/lunar eclipse conjunction question, although Iarrived at the explanation independently.In his book, Meeus also states that the occultation ofJupiter by the totally eclipsed Sun on June 30, 1954, was firstpointed out by H. O. Grönstrand in Stockholms ObservatoriumsAnnaler, Band 16, no. 2, p. 22. Readers of the JRASC shouldprobably be made aware of these facts.Warren MorrisonCavan, OntarioAstrocrypticby Curt Nason, Halifax CentreAcross1 Stellar stage evolved from poor gradient (3, 5)5 Avon calls back for the starburst pattern (4)9 Charge holder for captor about disturbed CIA (9)10 Type G transposed to Africa (5)11 Unethical memory returns in scrambled mail (7)13 Delta Eridanus, perhaps?
