D. A. Perley (LJMU) and Anna Ho (Caltech) report:

We observed the location of ZTF20abbiixp/AT2020krlNot found
 
 
 (Ho et al., GCN 
27799Not found
 
 
), the presumed optical afterglow of GRB 200524A (Fana Dirirsa et 
al., GCN 27797Not found
 
 
), with the 2m robotic Liverpool Telescope between UT 
2020-05-24 21:39 and 21:53.  We acquired 120s of exposure time in each 
of the u, g, r, i, and z filters.  Photometry is as follows (all times 
relative to the LAT trigger as reported in GCN 27797Not found
 
 
):

  t_mid(d)  filter  magnitude
  --------  ------  ----------
  0.6921    z       20.49 +/- 0.15
  0.6941    i       20.86 +/- 0.09
  0.6961    r       21.03 +/- 0.07
  0.6981    g       21.32 +/- 0.06
