SAO Moonwatch

From 1956-1975, the Smithsonian Astrophysical Observatory's Moonwatch program issued ephemerides for artificial satellites and collected observations from amateur astronomers. These observations were important in helping to keep track of satellite orbits as they changed over time. Observers from around the world participated in this program, including a number from Canada.

The Smithsonian Institution Archives list shows includes material relating to Canadian participation in the program and can be seen here (do a text search on "Canada").

Thanks to Eric Briggs (Toronto Centre) for finding this material.
