摘要
The NH(3)(1, 1) line emission was detected at -120 arcsec, + 60 arcsec offset from the star Cyg OB2 No. 12. The region had been initially mapped in 13CO(1 -0) and was called clump B. The subsequent detection of the CS(2 -1) line by the same authors led them to suggest that the clump could be an object similar to a Bok globule. The present detection and analysis confirm what was proposed before, that is clump B is a newly discovered starless Bok globule.
