Plaskett Report for January 1932


The month was below average for observing. On 9 nights with 49.0 hours observing 34 plates were secured. The 13-year average for the month shows 10 nights, 69.3 hours observing and 79 plates.

Approximately 115 persons visited the observatory during the month

Director J.S. Plaskett estimated the intensity of the K line on about 300 plates. Computed the dispersion in these estimates and the effect on the value of the rotational constant. Continued preparation of manuscript of Volume 5, Number 3 for printer. Usual correspondence, etc.

[Plaskett gave a talk to the Victoria Chapter of the RASC on January 29, 1932, Ed.]

Assistant Director W.E. Harper observed on 4 nights securing 20 plates. Measured for radial velocity 43. Determined orbit of HR 6290. Prepared summary of year’s work for Monthly Notices. Gave one lecture in Vancouver and one seminar talk.

[Harper’s January 16, 1932 lecture in Vancouver was given at the Canadian Memorial Hall and was titled “The Astronomy of the Poets”, Ed.]

Astronomer J.A. Pearce measured 22 plates for radial velocity. Completed paper for publications Volume 6, Number 6. Gave one seminar talk.

Astronomer C.S. Beals observed 2 nights obtaining 8 spectra. Fitted new lens to 3 prism spectrograph and tested for flatness of field. Spent the month largely in an attempt to apply the spectrophotometric data on Novae and Wolf Rayet stars to a determination of the temperatures of these objects.

Astronomer F.S. Hogg observed 3 nights, securing 6 plates. Measured 5 plates for radial velocity. Theoretical work on distribution in globular clusters. Preliminary work on measurement of radial velocities with photometer. One seminar talk.

Computer S.N. Hill did computational work on proper motion, position angles, τ and υ components, measurement and reduction of band spectra. Assisting in computational work, partial least squares solution and other related work on stellar motions. Preparing three radial velocity graphs for publication.

Clerk-Stenographer Miss L.M. Blake handled usual correspondence, accounts, reports, and envelopes for spectra. Typing Volume V, Number 3 and proof reading Volume 6, Number 3. Typing articles for press.

Astronomical Assistant T.T. Hutchison assisted in observing on 7 nights. Made camera adapter. Kept telescope in running order.

[Dr. Helen Sawyer Hogg, F.S. Hogg’s wife was also a respected astronomer. She gave a talk to the Victoria Business and Professional Women’s Club, Ed.]
