Plaskett Report for March 1927

The observing weather was a little poorer than the average for the month for while the same number of nights (16) were obtained as is the average for the eight-year period, the plates secured totalled only 127 as against the average of 164. The hours of exposure time was 105.6 against the average of 107.7

Director J. S. Plaskett worked 2 nights securing 24 plates and measured 32 spectrograms for radial velocity. Wrote a descriptive article of the observatory and its work for the ASP. Prepared material for a lecture on Clusters and Nebulae. Handled general correspondence and administrative work.

Assistant Director W. E. Harper worked 5 nights securing 48 spectra and measured 31 plates for radial velocity. Determined the orbits of twp spectroscopic binaries, Lal 428 and HR 839 and wrote up for publication.

Research Astronomer H. H. Plaskett worked 5 nights securing 16 spectra on 6 plates, 2 of which were long exposures. During the day, principally engaged in drawing up two detailed tables containing all the published and some unpublished work on the galactic nebulae, showing emission spectra. A preliminary discussion has already been made of the results for the diffuse nebulae.

Astronomer J. A. Pearce observed on 4 nights obtaining 49 spectrograms and measured 35 spectrograms for radial velocity. Worked on card index of radial velocities. Usual clock corrections and mixing of chemicals. Prepared and gave one talk before the staff.

Astronomical Computer S. N. Hill measured and reduced 15 B-type spectrograms for radial velocity. Work in connection with the library. Preparing table, excerpts from Witz’s table concerning nebulae. Work on period of binary HD 32990.

Senior Clerk Typist Miss H. R. Keay handled the usual correspondence, reports, accounts and plates. Read the galley proof of Volume III, Number 18 and page proof Volume IV, Number 1. Typed Volume IV, Number 2. Work on card catalogue of mailing list. Miscellaneous astronomical typing.

Instrument Maker Foreman T. T. Hutchison assisted in observing on 6½ nights. General repairs to the telecope.
