Model geometry of the observed globule hosting two embedded YSO and an internal embedded cavity/H II region. The relative sizes of the individual shells are not shown to scale. The external non-clumpy PDR is shown as yellow outer shell, the internal, clumpy PDR is shown as golden clump ensembles between the embedded H II region and the molecular cloud shown as gray spherical shell. The image projected on the bottom plane is Spitzer 8 μm emission (for orientation, the flux values are not of interest here). The offsets are given in arcsec referring to the position RA(2000) = 20h33m49.95s, Dec(2000) = 40°07′42.75″. UV-radiation impacts externally via the Cyg OB2 cluster and internally via the YSOs. The cavity radius is approximately 15″–20″, determined from modelling and consistent with the region of brightest IR emission.
