IAU Circular 8502 announces the following names for high-numbered moons of Jupiter: Jupiter XXXIX Hegemone = S/2003 J 8 Jupiter XL Mneme = S/2003 J 21 Jupiter XLI Aoede = S/2003 J 7 Jupiter XLII Thelxinoe = S/2003 J 22 Jupiter XLIII Arche = S/2002 J 1 Jupiter XLIV Kallichore = S/2003 J 11 Jupiter XLV Helike = S/2003 J 6 Jupiter XLVI Carpo = S/2003 J 20 Jupiter XLVII Eukelade = S/2003 J 1 Jupiter XLVIII Cyllene = S/2003 J 13 No pronunciation guide is provided, but since I am professional astronomers mis-pronouncing names more often these days, it is perhaps worth noting (maybe particularly for Americans) that all but one of these end with a long 'e' sound. Thus the penultimate name above should be pronounced 'you-ke-lah-dee'. Then all you have to remember is that this is moon number 47 around Jupiter. Between the Greek names and the Roman numerals, only those who didn't doze off in mythology class will find this perribly interesting.
