The Handbook for 1943 is the thirty-fifth issue. The times of moonrise and moonset, first printed last year, are now extended to include five latitudes, namely, 40, 45, 50, 52 and 54 degrees. The page of meteorological information for places in Europe and Asia is not given this year; but the tables of lunar occultations for Canadian stations appear again. Messier’s catalogue has been replaced by three tables giving more complete information about clusters, galactic nebulae, and extra-galactic nebulae.

Observer's Handbook 1939

WMacDonald's picture

PREFACE

In the Handbook for 1939, which is the thirty-first issue, numerous changes have been made. By giving the times of sunrise and sunset for every second day, although additional latitudes have been included, there has been a saving of six pages of space. This has allowed the inclusion of times of beginning and ending of twilight, of ephemerides of Saturn’s satellites and of the brighter asteroids, the extension of information on Meteors and Occultations, and the insertion of a table of miscellaneous Astronomical Data. The table of Satellites has also been revised.

Observer's Handbook 1936

WMacDonald's picture

Edited by C.A. Chant.

Twenty-eighth year of publication.

PREFACE

Following the example of 1934 and 1935, there is no list of stars occulted by the moon in the present issue of the Handbook. The computations for Toronto and Ottawa, published in 1931, 1932, demanded much labour which seemed hardly warranted by the results attained. Our country extends over so many degrees of longitude that predictions for a single place are of limited use. The Editor would be glad to publish brief lists for well distributed stations and asks for suggestions.
