Bochenek (LJMU) report:\n\nWe obtained imaging observations of the SVOM-detected GRB250419A (Wang et al., GCN 40168) with IO:O on the Liverpool Telescope on the night of 2025-04-19 between 22:02 and 22:26 UT.   6x100s exposures were acquired in both SDSS r-band and SDSS i-band.  We clearly detect the optical counterpart (e.g. Ocelotl López et al., GCN 40169; Xin et al., GCN 40170) at the following magnitudes, calibrated using PanSTARRS secondary standards:\n\nMJD     dt   filter  mag  +/- unc\n60784.91810  0.814  r  19.96 +/- 0.06\n60784.92664  0.822  i  19.76 +/- 0.06\n",
