We present the results of 12CO J = 1-0 line observations of eleven Galacticsupernova remnants (SNRs) obtained using the Seoul Radio Astronomy Observatory(SRAO) 6-m radio telescope. The observation was made as a part of the SRAO COsurvey of SNRs between l = 70 and 190 deg, which is intended to identify SNRsinteracting with molecular clouds. The mapping areas for the individual SNRsare determined to cover their full extent in the radio continuum. We usedhalfbeam grid spacing (60") for 9 SNRs and full-beam grid spacing (120") forthe rest. We detected CO emission towards most of the remnants. In six SNRs,molecular clouds showed a good spatial relation with their radio morphology,although no direct evidence for the interaction was detected. Two SNRs areparticularly interesting: G85.4+0.7, where there is a filamentary molecularcloud along the radio shell, and 3C434.1, where a large molecular cloud appearsto block the western half of the remnant. We briefly summarize the resultsobtained for individual SNRs.
