Predicted light curves of selected NEAs based on their postdiscovery orbit fits. Gray points show all ZTF images that should contain the asteroid. Candidate intersections (blue) are ZTF images in which the asteroid is predicted to be brighter than the image’s 3σ detection threshold. The presence of candidate intersections before the discovery date allows for significant arc extension. The points circled in red in the top two panels mark successful prediscovery detections in ZTF. They correspond to candidate sources with a likelihood significance greater than 10σ (see Figure 5). The bottom two panels demonstrate null detections: we artificially brighten the reported magnitudes for 2022 DB4 and 2022 ED1 by 5.3 mag but they are in fact undetectable in ZTF.
