About this observatory

The Louis B. Stewart Observatory, formally known as the Toronto Magnetic and Meteorological Observatory, stands on the St. George campus of the University of Toronto and is regarded as the birthplace of Canadian astronomy.

About Louis B. Stewart Observatory

The original log building was constructed in 1840 as part of a worldwide research project led by Edward Sabine to investigate fluctuations in Earth's magnetic declination. When the international project concluded in 1853, the Canadian government rebuilt the observatory in stone, and it went on to serve as the country's primary meteorological station and official timekeeper for more than fifty years.

History

Measurements taken at the Toronto site provided key evidence that sunspots were responsible for fluctuations in Earth's magnetic field, a significant contribution to 19th-century geomagnetic science. Wikidata records the observatory's founding year as 1855, close to the 1853 stone rebuilding documented in its history.

The observatory is located on the University of Toronto's St. George campus, in downtown Toronto, Ontario, Canada, in the North America region.
