Overview of the Serpens/G3-G6 region (also called Serpens Cluster B and the Serpens NH3 cloud) as seen by IRAC/Spitzer in 3.6 μm (blue), 4.5 μm (green), and 8 μm (red). N up, E left. Total FOV ≈ 15′ × 15′. The jets are mainly enhanced in the 4.5 μm band. The ≈4′ field monitored with NOTCam for proper motions is marked white and shown in Fig. 2. The white arrows point to two bow-shock shaped features outside our monitored field to the N and NE and two jet-like features in the SW region.
