L.B. He, X. Liu, Z.P. Zhu, J. An, S.Q. Jiang, D. Xu (NAOC), S.Y. Fu (HUST), J.P.U. Fynbo (DAWN/NBI), A.M. Kadela (NOT) report:

We observed the field of EP260602a detected by EP (Li et al., GCN 44770),  using the 2.56m Nordic Optical Telescope (NOT) equipped with the NOTCam camera. A series of J-band frames were obtained.

The previously reported optical counterpart candidate (Xu et al., GCN 44781; Watson et al., GCN 44790) was detected in our stacked image with J = 21.47 +/- 0.18 (Vega), at a median time of ~ 16.44 hrs post-burst, calibrated with nearby 2MASS catalog and not corrected for Galactic extinction.
