Radio surface brightness−diameter diagram for SNRs at a frequency of 1 GHz (black triangles), obtained from numerical simulations (Pavlović et al. 2018, their Figure 3). Our newly detected SNR G288.8–6.3 is marked with a red star in the lower right corner, while Cassiopeia A is shown with an open triangle. The open circle represents the youngest Galactic SNR, G1.9+0.3 (Luken et al. 2020). Numbers represent the following SNRs: (1) CTB 37A, (2) Kes 97, (3) CTB 37B, and (4) G65.1+0.6.
