L. Izzo (INAF-OACn & DARK/NBI), D. B. Malesani (DAWN/NBI and Radboud Univ.) report:

We observed the field of EP 240806A (Wu et al., GCN #37063) with the Sinistro instrument mounted on the 1-m telescope of the LCO network, located at Siding Spring Observatory, Australia. Observations started on August 06 at 10:30:58 UT (5.7 hours after the GRB trigger). We obtained a series of 3x180 s images in the r filter.

In the stacked image, we detect a new source within the WXT error circle at a position consistent with the source reported by Li et al. (GCN #37064).

We measure a preliminary magnitude of r = 21.9 +/- 0.2 mag (AB), calibrated against nearby stars from the Pan-STARRS catalog.
