We present a new survey of the third galactic quadrant in the J = 1 -
0 transition line of CO. With an angular resolution of 8.8' and a rms
noise temperature of 0.10 K, this survey has allowed the detection of
weak emission from distant molecular clouds, 12 - 18 kpc from the gala
ctic center, previously undetected in a low resolution survey of this
region done with the same telescope (May et al. 1988). Owing to the wa
rping of the outer Galaxy, the coverage follows a strip inclined to th
e galactic plane covering at least 3-degrees in latitude between longi
tudes 210-degrees and 270-degrees, but only 2-degrees between 194-degr
ees and 210-degrees. The results of the survey are presented in the fo
rm of a full set of latitude-velocity and longitude-velocity contour d
iagrams for each observed longitude and latitude, respectively. Spatia
l maps, obtained by integrating the CO over the spectral range where e
mission was detected, -19 to 110 km s-1, summarize the survey for comp
arison with continuum data (gamma-ray, infrared, and radio).
