Plaskett Report for October 1932

While the first half of the month was a continuation of the good weather in September, the latter half was very poor and the month stands a little below the average. On 15 nights with 101.3 hours, 76 plates were secured. The 13-year average shows 16 nights and 125.2 hours.

Approximately 406 persons visited the observatory during the month.

Director J.S. Plaskett made five solutions of the residual velocities of O and B type stars for rotational term and direction to centre with other computational work. Usual correspondence and administrative duties.

Assistant Director W.E. Harper observed on 6 nights, securing 48 plates. Measured for radial velocity 50. Translated several articles in German for seminar.

[Harper gave one of his regular radio talks on 17 October, 1932 on CFCT, Ed.]

Wed, Oct 19, 1932 – 13 · Times Colonist (Victoria, British Columbia, Canada) ·

Astronomer J.A. Pearce observed on 4 nights, obtaining 17 spectra. Measured 7 plates for radial velocity. Worked on photometric orbit of the eclipsing variable GO Cygni, and Volume V, Number 4.

Astronomer C.S. Beals prepared for publication results of past three years work on Wolf Rayet stars.

Astronomer F.S. Hogg observed 5 nights, securing 11 plates. Measured 6 plates for radial velocity. Measured intensity distribution in the bands of TiO and the contours of He and Fe emission lines in two spectra of Z Andromedae spectrophotometrically. Measured wave lengths on two plates of Z ANdromedae.

Computer S.N. Hill worked on spectra photometric reductions and plotting intensity curves of band spectra.

Clerk-Stenographer L.M. Blake handles correspondence, accounts, cheques, filing and library assistance. Computations and typing for 76 envelopes for spectra. Typing of articles for publication and broadcasting.

[Miss Lora M. Blake was absent from the Observatory for a few months and returned to her duties in October. For at least part of that time she was on vacation in Southern California., Ed.]
