FCRAO has initiated an imaging survey of CO J=1–0 emission from the outer Galaxy to better understand the physical properties of the molecular gas component of the interstellar medium and to determine the relationship of this component to spiral arm features. When completed in Spring 1996, the CO Survey will cover 103° < l II < 145°, −3° < b II < 5°, and −150 < VLSR < 50 km s–1 with angular sampling of 50″ and velocity resolution of 0.8 km s–1. During the first year of observations, we have focused upon two fields with longitude ranges of 103° < l II < 112° and 131° < l II < 139°. The first field corresponds to the Cepheus region while the second field contains the W3, W4, and W5 complex of HII regions. To date, 700,000 CO spectra have been collected. In this contribution, we present preliminary results from the first year of observations.
