摘要: We investigate the structure of a field around position V838 Mon as seen in lowest CO rotational transitions. also measure and analyse emission same lines at Mon.Observations have primarily been done J = 2-1 3-2 using KOSMA telescope. A 3.4 squared degrees has mapped on-the-fly mode these Longer integration spectra on-off obtained to study Mon. Selected positions observed 1-0 transition Delingha telescope.In we identified many molecular clouds. They can be divided into two groups from point view their radial velocities. One, having V(LSR) range 18-32 km/s, with Perseus Galactic arm. The other one, between 44-57 probably belongs Norma-Cygnus velocity is within second but object does not seem related any did find buble 1 degree dimension claimed van Loon et al. An detected very narrow (FWHM ~ 1.2 km/s) 53.3 km/s. Our analysis data suggests that extended.
