Plaskett Report for February 1928

Observing weather was still a little below the average in quality thought the number of hours observing secured was about the average. 99 plates were secured on 14 nights with a total exposure time of 85.4 hours. The eleven-year average is 13 nights, 83.2 hours and 117 plates. The mirror requires resilvering; its poor condition probably lessened the output slightly.

Director J. S. Plaskett obtained 20 spectrograms on 3 nights. Made drawing for Volume IV, Number 10; worked over literature in preparation for and made drawings to illustrate a lecture on stellar motions. Commenced revision and final checking of velocities of B stars. Handled the usual correspondence and administrative work.

[Plaskett gave an address on the motions of the stars at Victoria College, Ed]
Wed, Feb 22, 1928 – 13 · Times Colonist (Victoria, British Columbia, Canada) ·

Assistant Director W. E. Harper worked on 5 nights securing 65 plates, several being bright stars requiring short exposures. Measured for radial velocity 26 plates.  Testing out periods of some binaries. Reading over Volume 16 of Lick Publications. Two addresses given.

[Harper was elected President of the Royal Astronomical Society of Canada this month, Ed.]

Tue, Feb 14, 1928 – 1 · Times Colonist (Victoria, British Columbia, Canada) ·

Astronomer J. A. Pearce observed on 2 nights obtaining 5 plates. Measured 13 plates for radial velocity. Worked on catalogue to radial velocities of O’s and B’s. Prepared and gave one staff talk “Investigations oof Cepheid Variables”. 4 recent papers by Shapley.

Astronomer C. S. Beals observed 4 nights, 18.9 hours, obtaining 9 plates. Measured nitrogen lines in the region λ4300-4800 on 3rd order grating plates. Gave one seminar talk.

Astronomical Computer S. N. Hill spent time computing proper motion and position of proper motion vector – B stars. Work on star catalogue. Work in connection with library.

Senior Clerk-Stenographer Miss L. M. Blake typed and prepared for printing MSS. of Volume IV, Number 10. Typed addresses for Diretor, Asst. Director. and Seminar talks. Handled the usual correspondence, accounts, plates and library assistance.
