Caption: Figure 6.
Upper panel: sky plane error for 2021 DG1 on 2035 July 31, which corresponds to the first time it is brighter than V = 23. Fits of its orbit with (red) and without (blue) ZTF prediscoveries were propagated with a Keplerian propagator. Lower panel: zoom in on the sky plane error for the combined fit.
