A couple of days ago Jan Kalivoda commented on finding GMT by lunar altitudes. As far as I can see this method (and comparable methods) was discussed in "Navigation" and the "Journal of the Institute of Navigation"quite some time ago: Chichester,F., Longitude without time, in: Journal of the Institute of Navigation, Vol. 19 (1966), 106 -107 (with comments by D.H. Sadler, one time superintendent of HM Nautical Almanac Office, p. 107 - 109). Evans, J.J., Longitude without time, in: Journal of the Institute of Navigation, Vol. 19 (1966), 392 - 394. Sadler, D.H., Longitude without time, in: Journal of the Institute of Navigation, Vol. 21 (1968), 234 - 235. Ortlepp, Bruno, Longitude without time, in: Navigation (Washington), Vol. 16 (1969), 29 - 31. Wright, Frances W. , Examples of Moon Sights to Obtain Time and Longitude, in: Navigation (Washington), Vol. 18, 292 - 297. Kerst, D.W., Longitude Without Time, in: Navigation (Washington), Vol. 22 (1975), 283 - 292. Luce, J.W., Longitude Without Time, in: Navigation (Washington), Vol. 24 (1977), 112 - 115. Kerst, D.W., Comments on "Longitude Without Time", in: Navigation (Washington), Vol. 25 (1978), 87 - 90. Sadler, D.H., Lunar Methods For "Longitude Without Time", in: Journal of the Institute of Navigation, Vol.31 (1978), 244 - 249 (with a historical note pointing out that the Board of Longitude in 1802 resolved that it "will not in future take into their consideration any methods of ascertaining the Longitude founded on the Moon`s Altitude...). A short section on lunar altitudes can also be found in: H.M. Nautical Almanac Office, A Modern View of Lunar Distances, in: Journal of the Institute of Navigation, Vol. 19 (1966), 131 - 153 (p.133 - 134) Regards, Wolfgang Koeberer
