Light and vibration from traffic brought an end to the star mapping in 1917, and the observatory was closed in 1931 on the retirement of the resident astronomer, James Short. A commemorative plaque stands on the site in Observatory Park, Pennant Hills. (John Noble, "Red Hill Observatory Park", 1999.)Physical FormatPennant Hills
