Dominion Radio Astrophysical Observatory

The Dominion Radio Astrophysical Observatory (DRAO) is a radio astronomy site in British Columbia, Canada. Telescopes:

• Synthesis Telescope.
• John A. Galt Telescope (aka 26-Meter Telescope).
• Solar-flux monitor.
• Canadian Hydrogen Intensity Mapping Experiment (CHIME).
• Deep Dish Development Array (D3A, experimental).

The observatory dates from circa 1960 and was involved in early developments of radio astronomy, including very-long-baseline interferometry (VLBI), and produced two early catalogs of radio sources, Dominion Observatory 1420 MHz Source Catalog (DA) and Dominion Observatory 10.03 MHz Source Catalog (DB).
