AbstractAutomatic magnetic observatories at many locations across Canada sample the various components of the geomagnetic field once per minute and record the measurements in digital form on magnetic tape. The magnetic tapes are mailed once a month to Ottawa for processing by computer. This paper describes a system which permits the operation of a remote automatic magnetic observatory to be monitored in Ottawa at any time, by means of commercial telephone circuits.
