The Handbook for 1926 is similar to that for 1925, which was somewhat larger than those issued for some years before that date. The increase consisted chiefly in a comprehensive table embodying the most important information known regarding 260 of the brightest stars. This table was prepared by Mr. W. E. Harper of the Dominion Astrophysical Observatory, Victoria, B.C. As in past years, Mr. R. M. Motherwell, of the Dominion Observatory, Ottawa, supplies the list of stars occulted by the Moon.
The Handbook for 1925 is somewhat larger than those issued in the last few years, a table containing the most important information regarding some 260 of the brighter stars being added. This was prepared by Mr. W. E. Harper, of the Dominion Astrophysical Observatory, Victoria, B.C. There is also an account of the total eclipse of the sun of January 24, 1925, by Mr. R. M. Motherwell of the Dominion Observatory, Ottawa.
The Handbook for 1924 follows the same lines as that for 1923, but corrections to some of the tables have been made in order to bring them up to date. The general sketch of the planets will be found useful in giving a view of their phenomena during the entire year, while under the heading "The Sky for the Month" are given further details.
The Handbook for 1923 follows the same lines as that for 1922. The general sketch of the planets, it is hoped, will be found useful in giving a view for the entire year, while the detailed account for each month gives the observer the times for the phenomena each day.
The Handbook for 1922 follows the same lines as that for 1921. As Mars comes into opposition this year a fuller account of the motions of that planet is given, with suitable map and diagram. The map showing the path of Uranus is on a larger scale than that of last year, and will be found more useful for those who wish to follow its motion amongst the stars with a field-glass.
