Infrared emission from VRO 42.05.01 at 4.6 µm (top) and 12 µm (bottom), with the regions identified in Fig. 6 overlaid. The sweeps in position-velocity space from Fig. 8 are indicated with an ×. The features in red are those we believe are due to the SNR shock, and (some or all) those in cyan could be due to a pre-SN stellar wind. We note that the regions of swept-up mass occur along the shell of VRO 42.05.01. Both maps are taken from the WISE archive (Wright et al. 2010).
