We observed the location of the optical transient AT2024eju (Srivastav et al., GCN 35932) associated with the fast X-ray transient EP240315a (Zhang et al., GCN 35931; Chen et al. GCN 35951) in the near-infrared J-band with the Wide-Field Infrared Camera (WIRC, Wilson et al. 2003) on the 200-in Hale Telescope at Palomar Observatory.
Observations began at UTC 2024-03-20T04:27:45.313, roughly 4 days after detection in the X-ray. The observations consisted of a dithered set of 45 sec exposures for a total of ~30 minutes.
We detect a faint source at the location of AT2024eju with m_J ~ 22.5 mag (AB).
