We intend to perform spectroscopy of a subsample of the stellarpopulation embedded in two isolated star-forming globules (DR18 andECX6-21) in the Cygnus X region. For that, we were awared 3 observingnights with the CAFOS instrument on Calar Alto. The globules to bestudied were probably formed as a consequence of the erosion of thatmolecular complex by the energetic input of the luminous stellarassociation Cygnus OB2 and we want to test the 'triggeredstar-formation' scenario. The proposed observations are based onsuccessfull PANIC observations at Calar Alto from last year inaddition to a data obtained through a dedicated program that usesHerschel, SOFIA (Stratospheric Observatory for Infrared astronomy),and millimeter molecular line mapping. The observations with CalarAlto continue our study of several star-forming globules in Cygnus X(Schneider et al. 2016) and one particular in Cygnus X(IRAS20319+3958, Djupvik, Comeron, Schneider 2017).
