The region from l=139°.5-141°.0, b=-2°.5-3°.0 contains three faint Lynds Bright Nebulae. LBN 140.77-1.42 and the lower portion of LBN 140.07+1.64 are associated with an intriguing arc of neutral hydrogen at Perseus Arm velocities and morphologically associated CO and dust emission. Young stellar objects (YSOs) are found along the length of the H I feature, several with velocities indicating a connection with the features in the molecular and neutral material. The arc-shaped ionized emission from LBN 139.57+2.70 is associated with a hole in H I also at Perseus Arm velocities and contains a YSO at its edge. The hole is consistent with a wind-driven bubble blown by an early B star. This paper uses data from the Canadian Galactic Plane Survey to characterize these regions, studying the gas, dust, and YSO components of the nebulae and the sources of illumination for the ionized gas.
