NGC 2024 and the Associated Molecular Complex
The second most prominent source in the Orion region is NGC 2024 (W12, Orion B). It lies eastwards of the bright star ζ Orionis (the eastern star in the belt of Orion) and is seen in the sky together with the elongated filamentary nebula IC 434 and the small reflection nebula NGC 2023, although they are probably not physically associated. A photograph of the region containing all these sources is shown in Figure 5.1.1, and an Hα contour map of the same area is presented in Figure 5.1.2. A radio continuum contour map of the fainter area around NGC 2024 (mainly IC 434) is shown in Figure 5.1.3.
