Image Details
Caption: Figure 6.
The flux densities of HOPS 403 are quite constant with time, with little systematic change in different configurations. The HOPS 321 data show that its flux density increased by ∼1.5× in 2022 September and sustained this greater flux density in the higher-resolution configurations until the end of monitoring in 2026 February. This is consistent with the apparent change in flux seen in the images shown in Figure 7.
