Abstract:
We report the optical non-detection of AT2025dup.

We report follow-up optical observations of the transient candidate AT2025dup conducted with University of Nova Gorica's 40cm GoChile telescope. Following the discovery report of the transient, we conducted follow-up observations of the transient between 2025-03-09 and 2025-03-14, coordinated by the BHTOM.space network. The data were reduced using the network's pipeline. We report non-detections at 3-sigma upper limits listed below. Given the reported discovery magnitude, we conclude that the reported transient is likely a false alert.

Further details and the full photometric dataset are available for download by registered users of the BHTOM.space platform.
