1.  Canadian National Seismograph Network - [ CN ] 

DATES OF OPERATION:  	13 Apr 1992 to present.

SEISMOMETER TYPE:
Streckeisen Model STS-1V/VBB; STS-1H/VBB.  

DIGITAL FORMAT:
SEED(IRIS); SEED, GSEV2.X, MK2, CA (CNSDC)

EVENT DETECTOR ALGORITHIM:
At the Canadian National Seismology Data Centre (CNSDC), continuous data are
archived onto 12" SONY optical disk platters; the CNSN 4-band frequency
domain event detector creates a list of "refined detections" for further
post processing, including automatic locations.

COMMENTS:
The station had operated with Standard Station Network equipment (3 orthogonal 
Wilmore MarkII short period seismometers and 3 orthogonal Spregnether "Columbia"
long-period seismometers-photographic recording) from 30 November 1972 to 30
September 1991.  These same instruments had operated in a similar vault in the
immediate vicinity from 17 August 1963 to 22 November 1972 (station code FBC).
