ACKNOWLEDGEMENTS

The OBSERVER’S HANDBOOK for 1959 is the 51st issue. Three additions have been made: daily values of the sun’s selenographic colongitude, planetary appulses and occultations, and a table of the nearest stars.

Cordial thanks are offered to those who assisted with the preparation of this volume, Gustav Bakos, Barbara Gaizauskas, William Greig, Kulli Milles, David Sher, Isabel K. Williamson and Dorothy Yane. Special thanks are due to Gordon E. Taylor and the British Astronomical Association for data on planetary appulses and occultations, to R. M. Petrie and Jean K. McDonald of the Dominion Astrophysical Observatory for the compilation of the table on the nearest stars and to Margaret W. Mayall, Director of the A.A.V.S.O., for the predictions of the times of maxima of the long-period variables.

Our deep indebtedness to the British Nautical Almanac and American Ephemeris is thankfully acknowledged.
