X. Liu, Z.P. Zhu, D. Xu (NAOC) report on behalf of a large group:

We reported a weak optical counterpart candidate in GCN 45650. This candidate is a residual transient at the position of a known point-like source in Legacy Survey (LS), by image subtraction of the LCO image in w-band against the LS image in the r-band. Therefore, we caution that this candidate may be due to the filter difference when doing image subtraction.
