SiO (2–1) integrated intensity over the velocity ranges 3.0– 6.75 km s⁻¹ and 7.0–15.75 km s⁻¹, respectively, in the vicinity of the GCC source 1450 (shown as red and blue contours). The contours levels are 1, 2, and 3 K km s⁻¹ in blue and 2, 3, and 4 Kkm s⁻¹ in red. The background map is the integrated intensity of N₂D⁺, assumed to show the location of the core. The length of the red elongated structure is approximately 0.3 pc.
