TITLE: GCN CIRCULAR NUMBER: 36008 SUBJECT: Transient EP240315a: J-band observations of AT2024eju with WIRC DATE: 24/04/01 20:56:49 GMT FROM: nearley@caltech.edu Nicholas Earley (Caltech), Viraj Karambelkar (Caltech), Christoffer Fremling (Caltech), Mansi Kasliwal (Caltech): 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).
