The observing weather during the month was somewhat above the average for the month. On 11 nights with 76.7 hours observing 63 plates were secured. The corresponding numbers for the twelve-year average for the month are 10 nights, 64.4 hours and 71 plates.
Taking the year as a whole, it was like last year much above the average for on 217 nights with a total of1415.3 hours observing 1070 plates were secured. The corresponding numbers for the twelve-year average are 207 nights, 1272.4 hours observing and 1524 plates.
The local meteorological statistics indicate 114 hours sunshine above the average whilst the precipitation was 8.2 inches below the average.
Approximately 207 persons visited the observatory during the month, make a grand total for the year of 33,318.
[Not related to the DAO, but there was an article in the Victoria Daily Times that a mountain would be selected in California for a new 200-inch telescope. That mountain would be Mt Palomar and the 200-inch telescope would begin operation in 1948., Ed.]
