The observing weather was fair only. 77 spectrograms were obtained on 13 nights and parts of nights., although the dome was opened and observing started on 3 other nights without useful results. Progress in the office work has been satisfactory and important investigations have been considerably advanced.
[The Observatory hosted Saturday night star parties which proved to be very popular. The public asked the BC Electric Railway to run a special car on Saturday nights so they could visit the Observatory, This article indicates that such a car was put in service. Alas, the BC Electric Railway discontinued the route up Saanich Peninsula later in 1927, Ed.]
Director J. S. Plaskett obtained 18 spectrograms on 5 nights and measured 6 spectra for radial velocity. Made drawings of fixtures for office building. Recomputed mean parallax and absolute magnitude of O-type stars. Read the proof of Volume II, Number 16. Handled the usual correspondence and administrative work.
Research Astronomer W. E. Harper obtained 27 spectrograms on 5 nights and measured 4 spectra for radial velocity. Determined the spectroscopic orbit of 45 Aurigae. Completing preparation of Volume III, Number 1 for the printer. Spent time making enlarged transparencies for illustrations of paper.
