DRAO: Radio interference control zone sign

by Editor on 09/28/21

Riding up in the mountains between Oliver and Kaleden you'll come across this sign as you approach the Dominion Radio Astrophysical Observatory. It's a research facility founded in 1960 and located at Kaleden, British Columbia, Canada. (exact address is 717 White Lake Rd, Kaleden, BC)

Found this with a google search;
"The Dominion Radio Astrophysical Observatory was inaugurated in 1960 at White Lake near Penticton, British Columbia. The creation of the observatory was primarily the work of Carlyle Smith Beals, an astronomer who wanted to advance the field of astrophysics in Canada.

The first parabolic antenna, measuring 25.6 metres, began operating in 1960. It was mainly designed to operate at a wavelength of 21 centimetres, which corresponds to one of the spectral lines of hydrogen.

The study of hydrogen is of great importance to astronomers: hydrogen is the most abundant chemical element in the Universe, where it is present as a gas, and studying its distribution in the Milky Way can help astronomers reveal the structure of our galaxy. Radio astronomers at Penticton have been striving towards this goal since the first days of the observatory."
