Director J. S. Plaskett was absent on business until June 13. He obtained 9 spectra on 1 night. Made focus tests of new Ross lens and did work in preparation for a paper on “Camera Objectives for Stellar Spectrographs”. Administrative duties.
Research Astronomer W. E. Harper obtainde 51 spectrograms on 7 nights. Measured some new lines correlating line intensity with absolute magnitude and completed fine curves for same. Performed administrative duties in the absence of the Director.
Astronomer R. K. Young obtained 34 spectra on 6 nights for radial velocity and absolute magnitude. He continued work on absolute magnitude obtaining reduction curves giving relation between absolute magnitude and line intensity, and type to line intensity. Began reading off absolute magnitudes and parallaxes for F-type stars.
Assistant Astronomer H. H. Plaskett absent until June 27 at Mount Wilson. Obtained one long exposure spectrogram. Corrected proof of Volume II, Number 12.
Temporary Assistant W. H Christie obtained 22 spectrograms on 4 nights. Continued compilation of the Card Catalogue of Radial velocities. Measured 12 spectrograms for radial velocity.
Clerk-Stenographer Miss H. R. Keay handled the usual correspondence, plates and accounts. Read the proof of Volume II, Numbers 10 and 11. Read the page proof of the Descriptive Booklet on the Observatory. Kept transferring the record of periodicals to the new book and prepared volumes for binding.
