Schiminovich (Columbia U) report:\n\nWe observed the field of EP261025a (Yang et al., GCN 46025, Mandarakas et al., GCN 46026; Mohan et al., GCN 46028) in the near-infrared J band with the MDM InfraRed Astronomy inGaas Experiment (MIRAGE) instrument on the MDM 1.3 m telescope.\n\nObservations began at UT 2026-10-26T02:49:34 (28.2 hours after EP-WXT trigger) in the J band for a total exposure time of 3210s.\n\nWe do not detect any new source within the FXT localization error circle (Yang et al., GCN 46025). We obtain the following 5-sigma upper limit in AB magnitudes: J > 19.8 AB mag.\n\nMIRAGE is a new robotic YJHs-band near infrared imager for the MDM 1.3 m telescope. We thank the Mt Cuba astronomical foundation for supporting development of MIRAGE and MDM Observatory staff for supporting the observations.\n"
