We have studied S241 and IRAS 19529+2704 by mapping the J = 1 - 0 transition of 12CO. High-velocity gas is found in both regions, and is identified as new outflows. The physical properties of the outflows such as size, mass and mechanical momentum are derived, and the characteristics of the driving source are analyzed. A large scale rotation with an angular velocity of ω ~ 0.48×10-14/s is measured in S241. The results suggest that they are active massive star-forming regions, and the massive young stellar objects are the driving source of the outflows.
