Abstract:
A distance of 2.5 [plus or minus] 0.2 kpc is derived for the dark globule Lynds 810 using photometric data for foreground stars and star counts. It is argued that this globule is likely to belong to the Vul OB1 complex. Its cometary structure, like certain other features of dust-related objects in Vulpecula, appears to be the shock signature of a past disturbance originating from a region near l = 60[degrees symbol], b = +2[degrees symbol], which lies within the fossil H II region Lynds 792.
