The observing weather for the month was just about the average, a total of 97 plates being secured on 11 nights. The average number for the past six years is exactly the same, 97, on 13 nights. Near;y all the plates this month were secured on 5 good nights, an average of two ony being secured on the other six nights

Research Astronomer H. H. Plaskett worked two nights obtaining one long exposure plate of Vega and 14 other spectra. Day work has been spent in determining the size of tremor discs of stars and the variation of atmospheric dispersion and extinction with zenith distance. Some experimental work has been done on the collimation of the spectroscope.

Assistant Astronomer J. A. Pearce observed on 4 nights and obtained 42 spectrograms. Worked on the orbit of HD 1337

Astronomical Computer S. N. Hill measured and reduced for radial velocity 14 B-type spectrograms. Correcting Julian Day on plate envelopes and radial velocity cards. Assisting the Director on two nights of observing. Worked on the period of HD 214240.

Senior Clerk Typist Miss H. R. Keay handled the usual plates, correspondence, accounts and reports. Typed two orbits, HR 8257 and Cor. Bor. for Mr Harper. Typed an article for the Journal of the RASC.

Instrument Maker Foreman T. T. Hutchison assisted in observing on 5 nights
