H. Kumar, D. Hiramatsu, E. Berger, A. Villar, K. D. Soto, S. K. Yadavalli, M. Hussaini, A. Gagliano, C. Ransome (Harvard) report:

We used the LDSS-3 imager on the 6.5m Magellan Clay telescope to follow-up on our two potential candidates, see H. Kumar et al. (GCN #36263). We obtained 150-second r-, i-band images and compared them to those obtained in the previous night. We did not find any source at the location of these candidates after image subtraction performed between two epoch images, indicating the non-transient nature of the sources. Therefore, we conclude that both the sources are unrelated to the S240422ed and thus, can be ruled out.

We thank Marcelo Mora, Povilas Palunas, and the LCO staff for rapid execution of these observations.
